I just did a multisite install. I followed the direction for Plesk with some support from the hosting company (I'm not uber technical which, I admit, is undoubtedly part of the issue).
I can create a site from the network admin page but it serves a blank page. Additionally, when I go to the network admin dashboard, it says 0 sites even when I've created them from the other section.
I understand that the blank pages are indicative of a PHP issue. I've verified that the network site fields are in the database.
What other common, or not so common, causes should I be searching for?
Thanks!
