WARNING: plugins/CorePluginsAdmin/CorePluginsAdmin.php(41): Notice - Undefined index: enable_plugin_upload
I have been removing incompatible plug-ins and installing new ones from the marketplace. Everything seems to work OK but I get this message.
We ran into a similar error because we copied the piwik conf files from piwik 3.0.1 to 3.0.2 and the conf file was modified in 3.0.2.
Hmmm. I was under the impression that is what you are meant to do. I guess I’ll do a diff and see what’s going on.
