 * We just recently switched to two-site architecture and I believe this is the 
   first time anyone has added a user since then. We have separate themes on each
   site and wp-activate.php is crashing in the theme header.php when they try to
   access elements of $gantry. Here are the two error messages:
    `Fatal error: Call
   to a member function displayHead() on a non-object in /asa/web/kindlearts.ca/
   web/wp-content/themes/rt_hybrid_wp/header.php on line 14` `Fatal error: Call 
   to a member function get() on a non-object in /asa/web/kindlearts.ca/web/wp-content/
   themes/rt_ximenia_wp/header.php on line 24`
 * And corresponding lines of code, respectively:
    `$gantry->displayHead();` `$gpreset
   = str_replace(' ','',strtolower($gantry->get('name')));`

 * Switch to a different theme and see if that works.

 * Huh, I didn’t bother to try that because they’re separate themes, but you’re 
   right – it worked! I guess RocketTheme is doing something in common in all their
   themes that breaks. I’ll report the bug to them.
 * Thank you.

 * Just FYI, the theme on your main site impacted the network settings 🙂 So that’s
   why it can sometimes get daft.
