If I try to export my issues, like so:
(Print Report -> Then click either the web icon or the doc)

I get the following error:
APPLICATION ERROR #804
Profile not found.
Please use the "Back" button in your web browser to return to the previous page. There you can correct whatever problems were identified in this error or select another action. You can also click an option from the menu bar to go directly to a new section.
I have no idea how to fix it, and I can't seem to find it anywhere on the internet.
Mantis version:

Thanks!
