Issue with Ownership / Permission of ISPCP

[Macsloverd]

I have tried to search the forum for solutions but no luck, so I guess I have to post a new thread for this problem.

I have a production ISPCP 1.0.7 on Ubuntu server 10.10 which was running great without any issue. Then one day I was trying to install some PHP extension by using 'aptitude' and it suggested remove php5 (and someting else) first in order to install that extension (???), but I did not actually think about it so just hit Enter to confirm, then the whole web server was no longer working (of course, no php5). I realized this so I 'aptitude install php5'. web server was back but admin panel and websites were not working (blank page for admin panel, and other issues for websites depending on what system). Finally I found out that the permission is wrong so that apache2 (or ispcp) is no longer the 'right one' to control the website, so I used the 'set permission gui' script to fix it with no luck. Then I 'chmod -R 777 *' with ispcp gui and other website, then it worked. Later, I also 'chmod -R 755 *' && 'chown -R www-data:www-data *', it also worked but FTP and other related function did not because of 'permission denined'. So I guess 'apache2 is no longer vu2000' or 'ispcp is no longer vu2000'. My question is 'How can I change the ispcp or apache2 back to normal'?

Any help is appreciated and thanks in advance.
