Thread:Extension talk:OpenID/addExtensionField/reply

Thanks for addings this info, I will update the line in the download section. As you can see, the 1.18 is not formally supported ("1.17 → 1.18 n/a No information is currently available for these versions. Please check the talk page for user reports").

I suggest to run always the latest versions of MediaWiki and OpenID, if this is possible.
