I’m having the same problem
Both EE and the MSM module were downloaded today
Incidentally, the general config etting to turn MSM on never appeared, I set it manually in the config file.
EE info tab in the CP says
“The current version of ExpressionEngine is v2.1.0 Build 20101020 “
Is this an error, the download page says:
“Current Version: 2.1.1 - Build: 20101020”
