Here's how to fix this:
Open arcade/functions/functions.php
Find this line:
Code:
global $header, $vbphrase, $vboptions, $stylevar, $headinclude, $bbuserinfo, $session, $show, $pmbox;
Change to this:
Code:
global $header, $vbphrase, $vboptions, $stylevar, $headinclude, $bbuserinfo, $session, $show, $pmbox, $template_hook;
That should make your blog link show.
This also works if your Project Tools link is missing.
Mr Zeropage, I'm wondering if this change should become standard in the next release to account for the two new official addons, Blogs and Project Tools.
