Thread:Project:Support desk/Tags filtering does not work/reply (3)

This sort of error is caused by calling the parser recursively (for example doing $wgParser->parse from inside a parser hook, or $wgOut->addWikiText from a parser hook, which would break things in many other ways too). It can often be triggered by one extension, and then break output in another. Thus its quite possible this is not Cite's fault, but a different extension installed.

Could you try and find a minimal test case (if you can come up with an example of this bug on a page that only uses the cite extension, and no other extensions, that would be great)
