Since 1.11.1: Can't see any data

Hi,

Don’t know why yet, but this morning I log in piwik to check some stats and all Widget display 0 data.

I got no error, even Piwik mobile is not working. Everything was running fine last week…

I’m also having this error under Settings / Overview


There is an error. Please report the message (Piwik 1.11.1) and full backtrace in the Piwik forums (please do a Search first as it might have been reported already!).

I managed to resolv the issue for no data. The problem is coming from UserLanguage plugin. I just disabled it and everything works fine except of the error under Settings/Overview

You can safely delete the UserLanguage plugin. It is old and not needed anymore, it was superseeded by the LanguagesManager plugin a few versions back.
