OoohBoi Smarter Menu Not Working

A little off-topic as this is a different plugin, but still built by OoohBoi.

I’ve used it on a bunch of my sites and it hasn’t worked for a while now. I know there have been updates made to it and was wondering if anyone knows what might be wrong or has any suggestions to make it work.

There is no rollback option (even when using “WP Rollback”) and I’ve disabled all other plugins and have done the usual things to try and troubleshoot.

Thanks in advance for any help.
