stripos only exists in PHP 5.
You are probably running PHP 4.
You also are hiding/re-directing your error messages somewhere, and have
not gotten into the habit (yet) of reading the error log.
You'll need to read php.ini to be certain, and I can't REALLY be sure
where your error_log is on your server, but if you are completely confused
by what I've typed, try this:
tail -f /usr/local/apache/logs/error_log
Dollars to donuts says you'll find something about stripos not being
defined, once you find the error output.
For penance, you will practice starting your work-day with:
"tail -f /path/to/your/log"
several times right now, and be sure you start your work-day that way for
the rest of the week
:-)
