error when moving a topic

[Shyrax]

When trying to move a topic by checking its box then picking Move from the pop up bar, we get  "Something went wrong. Please try again." If we go into the thread and choose Move under the Moderation menu, it works fine. The only error log I see is a system log. It is below. 

 

Error: Class name must be a valid object or a string (0)

This sounds a lot like this thread:

You don't happen to be running PHP 8.1 by chance, do you?

Thank you for bringing this issue to our attention! I can confirm this should be further reviewed and I have logged an internal bug report for our development team to investigate and address as necessary, in a future maintenance release.

It’s not related to the mentioned issue.

The OPs bug was that one of his forums has a not exist style being set to override the users preference
