I am really sorry you were right, I have just found what the problem was after a bit of search, I'll correct automatically in the next version but here is the fix :

Here is how you can fix this unuseful query problem:

Go in your acp in the manager of plugins and edit the MGC chatbox plugin linked to the global_start hook.

Then remove from it :

  $parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list());
  $vbulletin->options['mgc_cb_annonce'] = $parser->do_parse($vbulletin->options['mgc_cb_annonce'], true, true, true, true, false, false);

Once this is done, validate and edit the one linked to forumhome_complete and add the removed code of above just after that bit of code :

if ($chatbox_permission && $vbulletin->options['mgc_cb_forumhome']) {

Then validate again, and to the same operation with the one linked to forumdisplay_complete after :

if ($chatbox_permission && $vbulletin->options['mgc_cb_forumdisplay']) {

Validate and do it again with the one linked to showthread_complete, after :

if ($chatbox_permission && $vbulletin->options['mgc_cb_showthread']) {

Here it is fixed no
