tables not being found

I have a ton of sites on my dedicated server. Suddenly, none of the bindings are working - not in the classic and not in the new mysqlil set up. I've checked about 5 sites so far. About a year ago, my server changed to MariaDB, and I ran into a few snags but with some adjustments, it was ok. This is a new problem.

The pages are still displaying ok, but I can't create any new bindings.

I am up to date, as far as I can tell with WA updates.

Any ideas? This isn't anything that the server gods will be able to assist me with.

Using GL6, Mac.
I checked server status and all systems appear to be "up."

I opened a ticket with server gods, and all systems are ok.
Anyone have any ideas?

I renamed Configuration file. I clicked on and off in extend manager for WA tools. Reopened DW, same results. Sites can not see any tables.
Getting desperate here. Anyone have any ideas?

Checking new Config files, there is a WA_DBScript.php script with a June 14, 2019 name. Is there a newer script that should be here instead?

I don't think the issue would be with that script. Give me a call and we can screen share to debug this and figure out what is going on.

ok...thanks!

Thanks for the solution, Ray!
Posting the solution for anyone else that may have encountered it.
At the beginning of the year, my server updated all its auto SSL certs. I have a redirect on my cPanel for all sites to push to https.
Evidently, DW6 code may be too old for newer SSL certs.
Ray changed the htaccess code to include the line that bypasses the auto redirect to mmServerScripts files.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{SERVER_PORT} !^443$
RewriteCond %{REQUEST_URI} !/_mmServerScripts/.*
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>

Hope that helps someone else!

Thanks again Ray!

Spoke too soon. I moved to another site to make this change but it wasn't successful. I'll try more.
Also not mentioned in above solution was to change the Manage Site server info to include https as one idea. It didn't work for me, however.
More when I have more tests.

Interesting development:
One site doesn't have anything in htaccess except the 401redirect and the db tables are fine.
more testing to follow

Further checking: the site that has no problem doesn't have the forced https in cpanel turned on. Server guys are looking at these notes also to see if they can spot anything.
