I just moved a website from a multisite installation (top level, no subdomains/subdirectories) to another multisite installation (not to primary position - but none of the other sites have any posts yet) on another server.
Everything has transferred over and seems to be working correctly except I cannot view all the categories with two of the plugins. I installed the plugins directly on the second multisite and didn't copy any plugin data or the wp_options table from the first multisite.
Two widgets that display categories are working correctly.
The standard WordPress category widget and Themify List Category widget work correctly.
I've tried deleting the plugins and re-installing them, switching to the default theme and turning off all the plugins, but they still don't work.
I'm at a loss as to why this would be happening since a few of the categories do show up, but the vast majority of them don't.
If anyone has any ideas on how to fix this, I'd appreciate it.
