6.4.11#64026-sha1:78f6ec4 version of jira. We can not attach such type file, txt, pdf etc works fine, but not jpg pr jpeg. IF I attach and save, it will goes to time out and: We have server version of JIRA (not cloud)
There was an unexpected error while loading the issue.
If you think this message is wrong, please contact your JIRA administrators.
After that it is not possible to open that issue any more. I can see the issue in backlog (or active sprint) but if I click it , it goes to timeout.
If I try to export it to excel, excel can not download it.
We just updated to this version of jira. Old jpg/jpeg files will open (attached before this update)
