Errors, e.g. "Plugin 'VisitsSummary' is not activated."


#1

Hello,

I had been having issues with Piwik for a while: various stats fail to show and instead there are a lot of error messages. I figured an update might help (my install was 1.2.something), so today I installed the latest version using this procedure. No hitches during the upgrade, but it hasn’t fixed the problem.

After I log in, the screen looks partly as it should, but:

(1) Under the time frame selection box there is the following error message:


WARN UserSettings[2014-07-08 13:42:46] [1f965] Failed to get data from API: Error: The report 'VisitsSummary_CoreMetrics' was requested but it is not available at this stage.

(2) In the ‘Plugins’ box it says:


Error: The report 'VisitsSummary_CoreMetrics' was requested but it is not available at this stage. (Plugin 'VisitsSummary' is not activated.)

When, for instance, I change the period to the whole year, I get the above messages 8 times, once for every info box presumably?

I checked that the files for VisitsSummary are indeed on the server.

I don’t know where I might ‘activate’ the plugin. I tried the ‘Parameters’ menu option (at least it’s called paramètres in French… the link is http://My.Server.Address/piwik/index.php?module=CoreAdminHome) but that too leads to errors:


Fatal error: Class 'Piwik_Plugin' not found in /users/MyUserName/www/piwik/plugins/ExampleUI/ExampleUI.php on line 28
 Piwik # Web Analytics
The class ExampleUI couldn't be found in the file '/users/MyUserName/www/piwik/plugins/ExampleUI/ExampleUI.php'

I am afraid I don’t recall what first caused these issues to appear… they seem to have grown worse bit by bit? Sorry for being vague about that.

Can anyone explain, and/or indicate a solution?

If there is no way to fix it – can I somehow do a ‘clean install’ without losing my data (if they are still there)?

Thank you.
