I have installed Plesk and paid for the upgrade. I have installed various domains and installed Wordpress on several of these and until now not had any issues. Today I installed a new domain. I installed Wordpress in Plesk. It said it was successful but then had Error 500 several times. I have been able to log in to Wordpress but it is dropping out every few actions and then having Error 500 again. I can’t find the reason and not sure how to fix it.
