Move thread and copy thread destination forum drop down empty

[KaitenV]

For some reason when I try to move a thread or copy a thread the destination forum drop down is empty. There should be lots of forums listed there. Please help.

The website is http://otakuhelpers.com:8080/forums

I actually have this same exact problem - it only happened after my 4.2.2 upgrade failed to even run. (or I upgraded the tapatalk to 4.8) - those are the only 2 things I did that could've changed this)

Any ideas..

What's weird is it works through the mobile app, but on the actual site - my dropdown is empty, it's really annoying.

I rebuilt everything through the admin as well - didn't help.

i have same problem on vB 4.2.5. I tried to disable all plugins, cloudflare, enable debug mode, cleared system cache, optimize&repair mysql tables, Rebuild forum information, reloaded page Ctrl+F5 but no change.
debug mode on the page (/postings.php) where one should select destination forum for the thread says on the bottom:
(unspecified) fetch_permissions(63, 1, 6); -> cached fperms for forum 63

Please can you help?
