Upgrading to v2.3.0 resulting in fatal error (Call to undefined method)


#1

I just upgraded to 2.3.0 using the in app upgrade. Immediately after I see the following error when trying to access any page:



A fatal error occurred
The following error just broke Piwik (v2.3.0):
Call to undefined method Piwik\Settings\UserSetting::isReadableByCurrentUser()
in
/srv/www/piwik/ana/plugins/LeftMenu/API.php line 28
If this error continues to happen, there is a good chance to fix this issue by disabling one or more of the Third-Party plugins. You can enable them again in the Plugins or Themes page under settings at any time.
If this error still occurs after disabling all plugins, you might want to consider uninstalling some plugins. Keep in mind: The plugin will be completely removed from your platform.

We appreciate if you send the error report to the Piwik team.

Please disable the LeftMenu plugin and refresh the page

Thanks Matt, but how would I disable it when I cannot access the admin interface? Is there a file/folder we can just rename/delete?


(Matthieu Aubry) #4

in your config/config.ini.php file, remove the line:


Plugins[] = LeftMenu

Thanks Matt, that resolved the error. Is this a core plugin? Is there any effect disabling it?
