Just in case anyone searchs on this topic. I kept
getting a blank page running a fresh install of
tikiwiki 1.9.x tiki-install.ph. Downgrading to 1.8.x
gave me a mysql_connect() error which tipped
me off to the problem. I was running a fresh load
of FC 4 which had a php, php_pear and mysql but
not a php_mysql connector. Doing a rpm query
should show at least:
# rpm -qa | grep php
php-mysql-5.0.4-10.5 <== this was missing
php-5.0.4-10.5
php-pear-5.0.4-10.5
Solution was to do a "yum install php-mysql".
It'd be nice if tiki-install.ph did some sort of test
that 1.8.x appears to have been doing.
