Debian 4 , no msql - imap servers found by scripts

Hi, Running a gpl VM on a Debian 4 , all fine, installed from a fresh system via script. All is working fine. But .. my sql is invisible to scripts like joomla, same goes for imap. The user created by virtualmin had no permission in webmin-mysql server, i've corrected manually the issue,but nothing, still the same problem. I tried to manually install a script in the base apache www root with my root credentials, nothing, sql seems dead, but is running fine. Any ideas about this issue on Debien ech?
