Hi
mfyvie, As you've already anticipated my 'global.php' file does indeed have the line
Code:
($hook = vBulletinHook::fetch_hook('global_start')) ? eval($hook) : false;
the same as yours, so it'll have to remain a mystery for the moment why is doesn't work. However I do run vBSEO 3.0.0 on my site so perhaps that has some involvement somewhere. I haven't explored all the options in vBSEO but if I find any potential conflict I'll let you know.... but for the meantime your manual edit to the 'onlineusers.php' appears to work fine.
Thanks again
Ron
