Our site is the latest WordPress
If you click into any product, it says Error Establishing Database connection. Same thing for admin page, etc.
We tried the usual plugin flush, .htaccess fix, etc, but no avail.
At least the front page is showing.
Problem occurred when we were testing something, turned off a lot of plugins, then turned them all back on.
Host is Stablehost, but they're not the most helpful at the moment.
We could roll back 30 hours, but since we're a WooCommerce site, we'll need someone to merge the orders.
We tried file rollback (not database), it was no help at all.
