Hi Bruno,
The "hosting space restrictions" of my client were the problem.
I removed some large files, and manually upgraded Modx by mergin the folders with the newest release, and it works now.
So I guess it didn't had anything to do with the plugin -although a comprehensible error log after failing the upgrade would be nice, or a "undo" button
regards
