I am running mediawiki 1.36.2 and when following Extension:TemplateStyles#Configuration

My site breaks after adding loadextenion

The error log is just getting http 500, but when I comment out load extension (template styles), the page loads fine

anyone have luck with getting templatestyles to work?

Please first upgrade your ancient, insecure MediaWiki installation - thanks.

Are you using the correct version for your version of mediawiki.

Do you have php set to show error messages (see How to debug)
