I’m having a multisite, I recently noticed that there will have errors when I updating the page. But, nothing goes wrong with the sub-sites. Only main site.

This the message I got when I deleting the page or updating the page.

There has been a critical error on your website. Please check your site admin email inbox for instructions.

When i refresh the page(while I’m deleting the page), I will get error message as below.

Error in moving to Trash.

Does anybody here encounter this issue before? How did you solve it?
