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.
