问题
I have a strange problem, I just installed my php web site on a shared hosting, all services were working fine. But after configuring my app I just could visit my web site only once, other attempts gives:
"The server is taking too long to respond.".
But from other IP i can access, but only once, it seems all ip addressess beeing blocked after first visit(even ftp and other services get down, no access at all from the IP), can anyone help to explore this problem ? I don't think that it's my app problem, the app works fine on my local PC.
Thanks.

First thing to try would be a traceroute to determine where your traffic is being blocked.
In a windows command prompt:
tracert www.yoursharedhostingserver.com

At the moment, trying to access this address gives this:
Fatal error: Class 'mainController' not found in /home/myicms/public_html/core/application/crApplication.class.php on line 181
I have tried it multiple times and it didn't block me. It might be that You have already solved this problem.
As far as I know, the behavior described by You could only be explained by a badly configured intelligent firewall. It may have been misconfigured by Your host.
If You visit a site at a certain host and suddenly You cannot access an ftp on this host, then it's either a (really bad) firewall or a (very mean) site that explicitly adds a firewall rule to ignore that address.
Some things that You might look into:
It might be something with identd too. What was the service You have configured on Your host? Was it by any chance any kind of server-controll panel (that might have an ability to controll a firewall)?
Is the blockade permanent, or does it go off after 24h, or does it only go off after rebooting the server? Does restarting some services makes the blockade go off?
Did You install any software that "protects Your server from portscanning"? It might be a bit too aggressive.
I wish You good luck in finding a source of this problem!

Chances are that if you can access it once that its actually working. The problem is more than likely in the php code than in the server.
