I have (almost) the same issue on more or less every ticket page.

When I go to any ticket page via the menue (e.g. "Open", "Assigned To Me", "Closed" and all others) I get this display error as well.
See here:

Interestingly when I click on the logo above the menue, which opens the same page again, the issue is gone.
So this is only when I open a page via the menue.

And the ticket list is also a bit broken on the version of the page where the display error occures.
See here 2 images for comparison:
Here it is "broken":

Here it is fine:

Note the missing icons in the second column and the tiny merge icon below the "Betreff" box in the broken view.

Hi guys, 

Please see this for the cause and a couple of solutions:

Thank you.

Am I right that there is a version of the Attachment Inline Plugin including a compatibility fix already included in osTicket Awesome?
That's cool.

I just realized that there is an attachment_preview.phar in the plugins folder and now I'm using this one instead of the zip file from the official repository.

Since then the issue is gone..
