On two Piwik installs I am running the menu item “Visitors” → “Locations” is labeled “Provider_SubmenuLocationsProvider” instead of “Locations”. This occurs if English or German are selected in the backend’s language settings, and possibly even in all other languages.
I have three Piwik installs. On one everything is fine and the menu shows up as “Locations” correctly. The two other installs are newer and have in common that they are used to analyze the stats of multiple websites. I am not aware of any other differences. All of them use the current version of Piwik (2.12.1) but the problem already existed in the past.
Any ideas on how to fix this are welcome.
