25 35 Eric Davis
h3. Why does Redmine use http links when I want it to use https links in Apache? (SSL)
26 35 Eric Davis
27 35 Eric Davis
This happens when Apache sending requests to a backend server, like mongrel or thin.  Apache isn't telling the backend server to use https so the links are generated incorrectly.  Add the following configuration to Apache:
28 35 Eric Davis
29 35 Eric Davis
    RequestHeader set X_FORWARDED_PROTO 'https'
30 35 Eric Davis
31 84 Holger Just
h3. I get this error message with a Passenger deployment: ActionController::RoutingError (No route matches "/index.html" with {:method=>:get})
32 84 Holger Just
33 84 Holger Just
Your Apache erroneously interprets the @public/.htaccess@ file which is needed for (f)cgi deployments. You can stop that by eiter completely removing the file (as it is not needed by Passenger) or by inserting the following configuration directive to Apache.
34 84 Holger Just
35 84 Holger Just

h3. I've created a new issue status but I can't use it, it doesn't show up in the status drop-down list.
40 7 Jean-Philippe Lang
41 8 Jean-Philippe Lang
Once you've created a new issue status, you need to include it in the workflow.
42 7 Jean-Philippe Lang
43 13 Jean-Philippe Lang
Say you have created a status named 'In progress' and you want the developers to be able to change bugs from 'New' to 'In progress'.
44 85 JC Wren
Go to "Administration -> Workflow", select 'Bug' and 'Developer', uncheck the 'Only display statuses that are used by this tracker' box then click edit.
45 86 JC Wren
You now see all the transitions allowed for developers on bugs. In the 'New' row, click the checkbox in the 'In progress' column and save.

50 36 Mischa The Evil
51 36 Mischa The Evil
Once you've created a new tracker, you need to "activate" it for a specific project.
52 36 Mischa The Evil
53 36 Mischa The Evil
Say you have created a tracker named 'Task' and you want the new tracker to be used for your project;
54 36 Mischa The Evil
* go to "(Project-)Settings -> tab 'Information' -> fieldset 'Trackers'",
55 36 Mischa The Evil
* check the checkbox of the new tracker 'Task',
56 36 Mischa The Evil
* and then click save.
57 36 Mischa The Evil
58 36 Mischa The Evil
You can now start using the new tracker 'Task' in the project for which you've just activated the new tracker.

66 37 Mischa The Evil
h3. The time calculations in "Spent time Reports" are wrong.
67 37 Mischa The Evil
68 81 Mischa The Evil
You are probably entering spent-time values in Redmine using "decimal time format":http://en.wikipedia.org/wiki/Decimal_time. See [[RedmineTimeTracking#Decimal-time-format]] for an in-depth explanation.

h3. Commits don't show up in the activity until I click on 'Repository'
73 12 Jean-Philippe Lang
74 12 Jean-Philippe Lang
By default, Redmine fetches the new commits from the repository only when you browse it.
75 12 Jean-Philippe Lang
76 12 Jean-Philippe Lang
If you want the commits to be retrieved periodically by Redmine in the background for all your repositories, uncheck 'Autofetch commits' setting and add a cron that runs (with appropriate environment):
77 12 Jean-Philippe Lang
78 87 Patrick Meidl
  rake -f /path/to/redmine/Rakefile RAILS_ENV=production redmine:fetch_changesets
79 12 Jean-Philippe Lang
80 47 Marco Bernasocchi
For SVN repositories you can also add the following command to a post-commit hook:
81 47 Marco Bernasocchi
82 47 Marco Bernasocchi
  ruby /path_to_redmine/redmine/script/runner "Repository.fetch_changesets" -e production
83 47 Marco Bernasocchi
84 52 George Montana Harkin
*Note, the second method of post-commit hook will slow down commits and could possibly cause commits to fail if Redmine is not functioning. 
85 52 George Montana Harkin
86 80 Daniel Widerin
You can bypass these disadvantages by sending the ruby-command to background.
87 79 Daniel Widerin
88 79 Daniel Widerin
  ruby /path_to_redmine/redmine/script/runner "Repository.fetch_changesets" -e production > /dev/null 2>&1 &

h3. I can't browse my svn repository through redmine
91 19 Thomas Lecavelier
92 25 Jean-Philippe Lang
Check the following:
93 25 Jean-Philippe Lang
* Make sure you're using a svn client and server >= 1.3. Redmine parse the -xml output from subversion, which is a svn 1.3 feature.
94 55 Alex Ford
* Make sure that the web app is able to run the svn binary. (hint: check your path and ensure the svn binary is on it)
95 53 Jan from Planio www.plan.io
* When using a file:/// link, make sure the system user under which Redmine runs has access to the location specified by file:/// on your local file system. (Hint: By default, when using passenger, Redmine runs as the user which owns your config/environment.rb.)
96 25 Jean-Philippe Lang
97 25 Jean-Philippe Lang
If you're accessing the repository over HTTPS:
98 25 Jean-Philippe Lang
99 25 Jean-Philippe Lang
The initial import of a subversion repository over https requires that the ssl certificate fingerprint be manually validated and stored in a config-dir accessible by the user running the web server. It is recommended that a directory local to the redmine application root be provided, either as a default (./svn/.subversion) or as a provided parameter in the repository settings for subversion.
100 25 Jean-Philippe Lang
101 25 Jean-Philippe Lang
The work around for the certificate acceptance issue is to manually checkout anything from the svn server specifying the local config-dir and accepting the certificate +permanently+.

* If you are using ruby 1.8.6:
137 44 Mischa The Evil
There's a bug in rexml 3.1.7 provided with ruby 1.8.6. You can fix it yourself:
138 1 Jean-Philippe Lang
In @ruby/1.8/rexml/document.rb@ (line 186), change: @if transitive@ to @if trans@ then restart the app.
139 26 Jean-Philippe Lang
See http://www.germane-software.com/projects/rexml/ticket/115 for details.
140 44 Mischa The Evil
* If you are using Internet Explorer:
141 44 Mischa The Evil
You'll need an SVG plugin like the one "Adobe provides":http://www.adobe.com/svg/viewer/install/beta.html to be able to display SVG-images properly within Internet Explorer.

h3. Global Wiki
150 78 Felix Schäfer
151 78 Felix Schäfer
There is currently no global wiki, and the current permission system won't allow one. A workaround is to create a project, if needed only with a wiki, and to use it for all global needs.

Make sure your SMTP server is properly configured or deactivate *email notifications* (remove @config/email.yml@) and restart Redmine.

h3. Emails use the incorrect url
162 48 Eric Davis
163 101 Mischa The Evil
The urls used in email is configured with the *[[RedmineSettings#Host-name-and-path|Host name and path]]* setting in Administration > Settings > General tab. It defaults to localhost:3000 (Ruby on Rails default). It should not include the protocol handler ("http://").
164 48 Eric Davis
165 62 Mischa The Evil
h3. Email notifications are not working
166 62 Mischa The Evil
167 62 Mischa The Evil
First, try to send a test email: go to _"Administration -> Settings -> Email notifications"_ and click _"Send a test email"_.
168 62 Mischa The Evil
It will send an email to the email address of your Redmine account:
169 88 Justin M
* If you get an error, check your configuration in @config/configuration.yml@. See [[EmailConfiguration]].
170 62 Mischa The Evil
* If you don't receive any email, check your SMTP server log to see if the email was properly relayed.
171 62 Mischa The Evil
172 62 Mischa The Evil
For other problems (eg. some people receive notifications but others don't), you can enable email debug output in your Redmine log file by commenting out this line in @config/environments/production.rb@:
173 62 Mischa The Evil
174 62 Mischa The Evil
175 62 Mischa The Evil
config.action_mailer.logger = nil
176 62 Mischa The Evil
177 62 Mischa The Evil
178 62 Mischa The Evil
After restarting the application, every email sent will be dumped to your log file (@log/production.log@).
179 62 Mischa The Evil
This way you can check the @To:@ field of emails to see if all the expected email addresses are present.

h3. All times are off by 1 hour after the daylight savings switched
182 21 Jean-Philippe Lang
183 21 Jean-Philippe Lang
Rails < 2.1 built-in time zone implementation doesn't handle DST. You have to install "TZInfo":http://tzinfo.rubyforge.org/.
184 31 Jean-Philippe Lang
To do so, run the following from your Redmine directory:
185 21 Jean-Philippe Lang
186 21 Jean-Philippe Lang
  ruby script/plugin install tzinfo_timezone
187 31 Jean-Philippe Lang
188 54 Jean-Philippe Lang
Do not install this plugin if you're using Redmine 0.8.

190 54 Jean-Philippe Lang
h3. What is the difference between Documents and Files?
191 54 Jean-Philippe Lang
192 54 Jean-Philippe Lang
The "Documents" section is for publishing specifications, notices, or other documents that do not belong in a SCM.
193 54 Jean-Philippe Lang
The "Files" section is for publishing versions of the tracked project, as a bundle (release).
194 54 Jean-Philippe Lang
195 54 Jean-Philippe Lang
h3. I get a 404-error when I try to view or diff a PHP-file
196 54 Jean-Philippe Lang
197 54 Jean-Philippe Lang
It's because Apache is seeing the extension @.php@ and tries to run the PHP-interpreter on the file. Since the requested URL isn't a real file, it returns a 404 error.
198 54 Jean-Philippe Lang
The solution is to turn off mod_php for your Redmine virtual host. That will cause Apache to call Redmine to serve up the file.
199 54 Jean-Philippe Lang
To do so, add the following lines to your virtual host configuration:
200 54 Jean-Philippe Lang
201 54 Jean-Philippe Lang
<pre><code>RemoveHandler .php
202 1 Jean-Philippe Lang
php_flag engine off    # Try without this line first

h3. Why are Textile inline styles not working?
206 64 Mischa The Evil
207 64 Mischa The Evil
Textile inline styles were disabled starting from Redmine version#2 for security reasons (see #2416).
208 64 Mischa The Evil
209 102 Dieter Egert
If you really need this feature and don't fear XSS attacks as you don't have projects with public write access, then you'll need to manually change the Redmine source (source:/trunk/lib/redmine/wiki_formatting/textile/formatter.rb@2192#L33), or you change this in /lib/redmine/wiki_formatting/textile/formatter.rb :
