Attachment bug

[Radosław Środoń]

Hello,

After updating jira server to version 8.19.0, the attachments were no longer displayed. We can download attachments from tciket, but after trying to preview the message "Ouch! We can't load the image.".

You mention "no longer displayed". Are we talking about the attachments showing on issue view but having no thumbnail, or are they not showing up in view at all?

Also you might want to tail the atlassian-jira.log file to see what errors are trailing underneath while you are trying to preview the files - it will likely throw an error of sorts.

This could also be a browser problem, particularly a lot of them happening with IE, which is a total holy grail of errors and bugs.

There is also https://jira.atlassian.com/browse/JRASERVER-72698 which appears to have come up in 8.15
