$tmp_database_path of type WP_Error is incompatible with the type string expected by parameter $tmp_database_path of GetPaid_MaxMind_Geolocation::update_database().

It seems like $tmp_database_path can also be of type WP_Error; however, parameter $path of dirname() does only seem to accept string, maybe add an additional type check?
