Thanks for getting back to me.
This is a multi-site WP instance if that makes a difference?
In the batch of updates I updated
404 Solution
Anti-Spam by CleanTalk
Fonts Plugin
Kadence Blocks
MailPoet
Rank Math SEO
After this batch update when I visit the child site with the PPWP plugin active WP crashes with the usual something went wrong error
I then activated Debug and tried again and saw it was PPWP error
and noted the RankMath reference, so rolled that back and tested and everything was working. I then rolled back all the plugins and upgraded RankMath again on its own and the crash happened again.
I’ll re-test again and get more logs over by email.
