How to do security now with DataBrige 2

HI Ray, Thanks for your help. I'm trying to update security for an admin area on the same site. I think I have 2 iterations of security on the admin folder. One was the old KAT which Adobe bought but I also have pages that use WA security assist. I think they are the newer ones. However when I try to login to the new one, I get this error: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

Also, when I try to load the WA Security to manage the pages, the database seems to take so long to load that I have to force quit. The page also says "Security assist (prior version) I notice that with the New Dbridge there is also User Authentication under the MySQLi tab. And am not sure which one I should be using to make sure the logins are compliant with the php 7, or the best way to update the security.

Also, when I opened the Security Assist > Create Security Pages, the whole DW 2020 seemed to time out.

Any suggestions on how to proceed?
