I set up a new WP 3.1 site last night and installed UAM. All was fine.
Today I tried to install YAPB and when I tried to activate it my admin crashed and I got a blank screen except for this message:
Fatal error: Call to undefined function get_userdata() in /home/kelly50/public_html/wp/wp-content/plugins/user-access-manager/class/UserAccessManager.class.php on line 1864
I deleted YAPB from cpanel and everything is fine again. IDK if this is an issue with UAM, YAPB, or if you just can't use these two plugins together.
BTW I also tried WP jquery lightbox on this site and the lightbox didn't work at all, even when I manually added rel="lightbox" to the links :(
What's everybody's favorite plugin for making photo galleries?
