I upgraded from a very old version (25?) to 1.35.0 and get an internal error. I don't know what wikimedia services are but it sounds like I dodn't need it at all.

MediaWiki internal error.

@Subfader Why would you move to an outdated insecure ancient version (1.30) with known and public security vulnerabilities, instead of upgrading to a supported and secure version?

Sorry, 1.35.0 ;)

whats the code/extension defining the wfbreakExtension() function and what hook is it using?

At a glance it looks like its calling $wgParser (which creates a new parser) while executing a Parser initialization hook, which is causing a loop. If the extension is being passed a Parser, it should use that instance instead of $wgParser.

Thanks, it was a mini extension I had added directly in LocalSettings and didn't recognize.
