Visitor logs don't work after update to 1.11

Hi everybody,

after upgrading to version 1.11 the visitor logs don’t work anymore (seems like loading forever). All widgets including the visitors also don’t show anything.

Already tried emptying the “tmp” folder as well as deactivating GeoIP just to exclude these error sources, but unfortunately no success.

Any kind of suggestion much appreciated.

Kind regards

Do you have any error logged in the server error log?

Short update: problem solved!

Simply disabling the UserLanguage plugin solved the issue (301 Moved Permanently).
