If you are still seeing this i would suggest reaching out to the support team directly to take a look at your account. https://support.ezoic.com/kb/article/guidelines-for-contacting-support
It depends what the error is you are seeing. I would suggest sending the team a screenshot of the error and explaining if this is showing when you first go to wp-admin login page or after you login.
It may be cause by a plugin, or could be missing lines from htaccess. file
