Debian with ISPConfig, problems with php after installing phpmyadmin

Hi all, i got a strange problem.
Untill yesterday my server read php files on both port 80 and 81
After I installed phpmyadmin for ISPConfig and UebiMiau Webmail I can access on www.clistere.com:81 to work on ISPConfig panel without problem...
but if I browse www.clistere.org/home.php ... apache doesn't read php file! This is for each php file on port 80.
Don't know if is involved firewall...
How could it be? Can somebody help me please?
Firewall iptables -L give this:

Chain INPUT (policy DROP)
target prot opt source destination
ACCEPT icmp -- anywhere anywhere icmp time-exceeded
ACCEPT icmp -- anywhere anywhere icmp source-quench
ACCEPT icmp -- anywhere anywhere icmp destination-unreachable
ACCEPT 0 -- anywhere anywhere
ACCEPT 0 -- anywhere anywhere state RELATED,ESTABLISHED
ACCEPT tcp -- anywhere anywhere tcp dpt:ssh
ACCEPT icmp -- anywhere anywhere icmp echo-request

Chain FORWARD (policy DROP)

Thanks a lot.

 

It's working for me, so I guess you got it fixed?

 

Yes I fix. I don't know exactly what happened. I got some stupid cache browser problem too.
Thanks a lot falko.
