Articles tab does not display hits. Cause: global var $mosConfig_hits (or $mosConfig_show_hits) for some reason disappears and does not get pass to the function getDisplayTab($tab,$user,$ui) when this function is invoked. My temporary fix is:
function getDisplayTab($tab,$user,$ui) {
global $database, $mosConfig_hits,
$mosConfig_offset, $mainframe, $my;
$return="";
// --- Retrieve $mosConfig_hits here
$contentConfig = &JComponentHelper::getParams( 'com_content' );
$config_vars = get_object_vars($contentConfig->toObject());
$mosConfig_hits = $config_vars;
// ----
....
}
