Thread:Extension talk:Semantic Social Profile/Crash on install

Hi, When I try to install this extension, my wiki turns blank when I go to “Special:SemanticSocialProfile”. I have SocialProfile, Semantic MediaWiki (without shell access), Semantic Forms and ParserFunctions installed, and they all appear in "Special:Version" before I install SemanticSocialProfile. Does anyone has the same problem and finds a solution ? Thanks Fred
