XenForo "No data received" error

[Zaddion]

My website runs on XenForo 1.4.5, I'm getting this error "No data received" when I try to install this addon:
https://github.com/s9e/XenForoMediaBBCo ... ster/build
Official link: https://xenforo.com/community/resources ... pack.2476/

I looked up the no data received error for XenForo and the devs of XenForo said:
"It's likely PHP crashing or (probably more likely) being killed for some reason, perhaps for taking too long. Do you notice a slowdown when it happens?

If it's random, it's almost certainly a server issue."

It requires PHP 5.3 or newer, which I do believe my site has the newest version of PHP. Any ideas?

Steam Authentication & Integration returns this error when people register with their steam account too, which is also a major problem. However it only returns this error sometimes, otherwise it'll return "Lost Steam ID" error. But other than that, it's the only other addon that returns this error. I've never had an addon return this error while installing though.

XenForo has a built-in caching system, I've rebuilt the caches for:
XML Sitemap
Search Index
Forum Information
Thread Information

and I also ran a "Clean Up Permissions" thing, which is:

"This will clean up any permission combinations which are no longer in use. This can speed up permission update and rebuild operations and remove unused data from the database."

I initially had problems with Xenforo and NFO web hosting. I think it had something to do with APC settings. Take a look thru this old thread and see if it helps.

Thank you so much! Disabling APC fixed all of my issues with XenForo!
