Grid view not working, TypeError /manager/assets/modext/core/modx.js

I have a installation of ModX 2.5.8 and include a Evo installation with GoRevo.
All works fine.
When I get a grid list e.g. at Batcher or Collections I see a empty list.

I get following Javascript Error in the manager:



Any idea?

Did you try manually deleting all files in the core/cache directory?

Clearing your browser cache and cookies is another thing to try.
