Hi Marcus,
I followed your great tutorial about the installation of Elgg Multisite for the 1.8 version. Everything works nice, except I can see these lines on my page when upgrading the application :
Notice: Undefined property: stdClass::$elggmulti_link in /var/www/atheneo/docroot/engine/lib/multisite.php on line 295
Notice: Undefined index: dataroot in /var/www/atheneo/docroot/engine/lib/multisite.php on line 32

Notice: Undefined index: enabled in /var/www/atheneo/docroot/engine/lib/multisite.php on line 32
Do you know why this problem occurs ?
