Using Umbraco 6.2.5. Had been on uComponents 5.5.0. Installed uComponents 6.0.0 and BOOM, I get a parsing error from ALL xslt's. Front end as well as when saving in the backoffice.

Error occured

System.ArgumentException: An item with the same key has already been added.

I can't find a solution online for this one. Any ideas out there? uComponents compatibility matrix says 6.0.0 should work fine with Umbraco 6.2.5.

Thanks,
