Hi there,
When I try to click on the "arrows" to manually sort my K2 Items, I get an error. Once I get the error, I can not get back to my K2 Items at all, I just get this error (screenshot) page. However, if I log out and log back in, I can see my K2 Items again. Any help would be greatly appreciated.

Hello,

Which versions of Joomla! and K2 are you using?
Any 3rd party K2 extensions?

Joomla 3.8.1
K2 2.8.0

Third Party Plugins
AllVideos
Simple Image Gallery Pro
JA K2 Filter
Inceptive Multiple Categories for k2

Thanks!

Hello, Can you try temporarily disabling JA K2 Filter and Inceptive Multiple Categories for k2 in order to find the culprit?

It was indeed Inceptive Multiple Categories for k2. I disabled it and then I could do a manual sort. When I enabled it again, I had the same issue. It looks like Inceptive Multiple Categories for k2 is not being supported, but I need the functionality. Any suggestions?

Thanks!

You try reaching the dev directly for a proposed fix or you can address the issue to a dev like JoomReem.
