Server goes down while trying to install WHMCS

I just setup LAMP on Ubuntu 14.04 x64 server and tried installing WHMCS. But every time I try, the server goes offline. Unable to understand what could be the issue. I even disabled firewall (UFW) but no success! I’m able to install WordPress but not WHMCS!
Can someone please throw some light on possible causes and remedy?

Hey there,

It sounds to me like you may be running out of memory. The next time that happens, you should take a look at the web console and click in and type a key or two to refresh the screen, you may see an Out of Memory error. If that is the case, you may want to resize to a larger memory size.

Happy coding,

  • Hi @jschwenn

    I figured the culprit was xCache. As soon as I removed it, WHMCS started to respond. Interestingly, xCache doesn’t hinder WordPress and works like a charm. But seems like WHMCS has some compatibility issues with xCache. Now I use APC.
