Greetings. I've been using MediaWiki in a couple different installations
for over a decade, but I've just run into a problem that has me stumped. It
came after upgrading from 1.29.2 to 1.35.1. The process seemed to go
smoothly, though I had to set the $wgServer variable which wasn't in my
LocalSettings.php. Now I get a persistent message that MediaWiki can't
access the database. Of course I've checked and double checked that the
database name, username, etc. are correct. I can access the database just
fine, but MediaWiki can't. I am using my old LocalSettings.php and wonder
if there could be some other problem there.
Pasting the errors below. Any help is much appreciated.
Sorry! This site is experiencing technical difficulties.
Try waiting a few minutes and reloading.
(Cannot access the database)
