Thread:Extension talk:WikiLove/Not working in MW 1.19.11

Hi, I've installed the extension, run the update (through the web, since I have no root access) and the extension seems to be working: at least, the checkbox in preferences appears. But if I check the box, as I visit an user page the server returns nothing. Other pages are ok.

THe production wiki is MW 1.19.11, but I have a local installation for tests wich works fine, and it's 1.24.

Does anybody knows if this is a known problem and how to make the extension run?
