Thread:Extension talk:WikiSEO/incompatible with mediawiki 1.20.2/reply (2)

This extension hasn't yet been tested with 1.20.2. At the moment it's only compatible with 1.19.0. It looks like a simple fix, I'll try to get to it asap. I'd advise you to star/watch the github repo and keep an eye on it for updates. If you fix it yourself please feel free to make a pull request on GitHub and I'll merge it in.
