I found an easy way to remove the dynamically created forum menu for forum v2.7 and use the block menu in GL1.4.1
here it is...
you need to ftp your forum config.php found in geeklog/system/plugins/forum to your local machine and open it with your text editor
then scroll down to line 120 and find this code:
Text Formatted Code
if ($pi_version >= 2.6) {
/* Retrieve the list of blocks to show on the left side and make the forum menu the first block */
$CONF_FORUM['leftblocks'] = array ('forum_menu');
$CONF_FORUM['leftblocks'] = ppGetUserBlocks($CONF_FORUM['leftblocks']);
on line 3 in this code where it says
= array ('forum_menu');
make it look like this
= array ('');
This will stop the forum from applying it's own menu and don't forget to make sure your forum block is enabled or you won't see one.
Good Luck,
Dennis
