I have been moving my site around lately from vps to vps in order to try and find a stable one and with every single one of them I managed to get Opcode APC running with FastCGI enabled.
I have a VPS with WHM/cPanel installed so installing and getting it running was pretty easy. Since I wasn't satisfied and I suspected the host was overselling the server my VPS was on (it was on OpenVZ) I decided to move it to another host that runs his servers on Xen.
Now, I followed the same steps I did to get APC Caching running with WordPress and W3TC installed, but the moment I set FastCGI as a PHP Handler my site can't load anymore. I can't even access the WordPress Admin area!
I have the APC module installed, MPM Worker and Mod_fcgid enabled in Apache. (I have also tried it without MPM Worker without success.)
Any ideas how to fix it? I'd really like to speed my site up to the max!
