Ugh - how do I figure this one out?
On Virtualmin GPL, I have several wordpress sites that, since last night, have been responding intermittently with "Error establishing a database connection" when accessed.
One moment they load fine, the next I get the error. Happens in both front and back end.
However, I can access the database with phpMyAdmin repeatedly with no trouble at all. Everything pops right up, no errors, no tables are reported as broken....
Virtualmin 4.06 CentOS Linux 6.5 mysql 5.1.73 WP 3.9 (been running 3.9 for about a week, no problems until last night)
