I just downloaded the latest tgz (nightly build) of moodle and I can't seem to add a new user. It says "Could not start a new user!
Here are some version information:
MySQL Version - 11.18 Distrib 3.23.53a, for pc-linux-gnu (i686)
PHP Version - 4.2.3
Apache Version - Apache/1.3.27 (Unix)
Moodle Version - 2003032602 (nightly tgz downloaded April 11, 2003 4:00PM EDT)
Everything else looks good. Database upgrade went smoothly and nobody has complained yet.
