Thread:Extension talk:Semantic Glossary/blank Mediawiki after installing Semantic Glossary

I have installed Semantic Glossary the way it is described. I also have Lingo 0.2 and Semantic Mediawiki (1.5) But once I install Semantic Glossary, I get a blank Wiki page. That means: nothing works. Not error message, nothing. The extension page says that Semantic Mediawiki 1.6 is required, but the official latest version is 1.5 So what could be wrong? Any help is greatly appreciated. Anja
