I have websites using the Wordpress platform. In the past few days, I have started getting errors on at least 2 of the websites. I can log on to the Admin Dashboard, but if I try to update a plugin or view a form entry, it will send me to a 404 error page.
I have reviewed, deactivated, and reactivated my plugins (the websites only share one common plugin). I have refreshed my permalinks. I have checked the .htaccess files. I have checked file permissions.
I know the server is accurately reading php and html files.
AND, if I refresh my browser a few times, the error will eventually get “unstuck” and allow me to go to the task I requested.
It is not happening on the frontend. Only when I am working on the backend.
Any thoughts on where else to look for the issue?
