Problems after upgrade to 1.11

As BigStu in 301 Moved Permanently after upgrading my piwik to 1.11 my visitors log can’t be loaded in any of my sites.

Taking a look to the developer toolbar I can see that the call to the activity log page is returning a 500 header.

If I check my apache error log file I can see the following line:

PHP Fatal error:  Cannot redeclare Piwik_LanguageTranslate() (previously declared in plugins/UserLanguage/functions.php:17) in plugins/UserSettings/functions.php on line 285

I also have a 500 header when I try to access the new “Real-time map”, caused by the same method redeclaration.

And if I select an interval of more than 4 or 5 days (varies depending on the amount of visits) I also get this error and no widget is loaded.

Disable the plugin UserLangauge and try again

Thanks! It solved the problem.

Now I’ve seen that if I access into the BotTracker config it throws me this error:

 error. Please report the message (Piwik 1.11) and full backtrace in the Piwik forums (please do a Search first as it might have been reported already!).

I tried to delete the cache in templates_c to discard, but there was no way…

PS. Can anybody tell me where is the search on this forums? I’m feeling like a dummy trying to find it xD
