MediaWiki upgrade problems
The Problem

My wiki is hosted on GoDaddy. I used Installatron to create the original installation.
When I upgraded to version 1.35 and 1.36 of MediaWiki, all I saw on the welcome page was undecipherable strings of ASCII characters and symbols. The page was completely illegible and unintelligible.
Solution for MediaWiki 1.35 upgrade
Disable output compression in LocalSettings.php:
## Uncomment this to disable output compression $wgDisableOutputCompression = true;
