Thread:Extension talk:Semantic MediaWiki/Cannot install core SMW2.0 extension on MW1.23/reply (4)

I'm not installing a different version or upgrading, I've just tried to install SMW and some of the other related extensions in the SemanticBundle and I'm getting the errors shown above. When I sadi "I've tried dropping SMW back to 1.9" what I meant is that I've tried the entire installation operation from scratch using Semantic Bundle that comes with version 1.9 of SMW.
