|Wiki URL||any wiki hosted on Miraheze|
List of steps to reproduce (step by step, including full links if applicable):
- Visit a page on any Miraheze wiki
- Watch as it acts completely random or crashes entirely
What happens?: Page freaks out, sometimes with a messed-up layout, sometimes with an internal error, and sometimes refusing to load entirely.
What should have happened instead?: Page renders normally.
Browser information, screenshots and other applicable information: This will probably stop happening once the upgrade is complete, but you'd expect wikis to be completely readable with no issues during upgrades, just being locked from editing. These issues are something to keep in mind for future MediaWiki upgrades.
