[SOLVED] Attachments can not be download and we can not see them added

Hi,
I have a probleme, the attachments added to projects and to activities can not be download and we can not see them, we only see the number of attachments.
You can check the picture attached.

Thank you.

Same issue here.

I don't know if it's the same issue but when uploading on test case (may affect other elements), no attachment appear, I have this error:
2015-11-03 13:33:00.039 ***** ERROR ***** ERROR *****
2015-11-03 13:33:00.039 ***** ERROR ***** on file '/var/www/prod/tool/file.php' at line (176)
2015-11-03 13:33:00.039 ***** ERROR ***** cause = mkdir(): Permission denied

I see 0 attachments on my administrator session and the user who uploaded see what is in screenshot.

The user uploaded attachment #93 and then uploaded attachment #94 so the (1) count is wrong also (the count was wrong because it didn't refresh, now I see (2)).

The funny part is that the files are successfully uploaded on the server in a new attachment_XX directory.

(Edit: no special characters in filenames btw)
(Edit2: Looks like it's an issue with the thumbs directory, but I can't find any parameter to change thumbs directory, where is it!? You shouldn't block application when there is an issue with thumbs. It's a shame there is no thumb but it's better to have access to the full file )

Actually, I moved the directory "files/" outside web access (except for report) so giving access to the outside web access thumbs/ directory was pointless since the directory was hardcoded ^^
