Redmine

Hi,

When uploading files or attaching files to issues, wiki, Files, Documents etc, getting Internal Server Error in Redmine. Please find below the error in log.

Started POST "/uploads.js?attachment_id=1&filename=Photo0735.jpg" for 10.0.14.2 at 2014-08-13 16:08:31 +0000
Processing by AttachmentsController#upload as JS
Parameters: {"attachment_id"=>"1", "filename"=>"Photo0735.jpg"}
Current user: 0001989 (id=33)
Completed 500 Internal Server Error in 406.0ms

TypeError (can't convert Array into String):
app/controllers/attachments_controller.rb:88:in `upload'

I am unable to root cause and have searched extensively in net and couldn't find a solution.

Please help on this.
