Publish Button Doesn't Work

Hi! I'm a relatively new user with a Wordpress site with:

GeneratePress Premium
GenerateBlocks Pro
Post X
Caching through WP Rocket

I've scoured the support tickets for a similar issue but can't find it, so am hoping you can help.

The problem is simple. I can't use the regular Publish button in the editing screen. It's blue, like it should work. I go through all of the pre-publish checks (and have also deactivated that option to experiment). But, whenever I click it, nothing happens.

I have to save the post as a draft and then go to the posts list ad publish it from the quick edit area.

It's a decent workaround, but I get worried I'm going to lose content or save something I shouldn't.

Does it have to do with wp rocket caching or do you have a recommendation? My site is https://otlseatfillers.com.

Thank you!
