This error is bizarre but after running the "yum install php-devel" command (after a long day of trying to install Facedetect and OpenCV for face detection) my site stopped functioning. The site uses mysql and php. When you hit the url, the page executes the mysql and the php, but it appears to randomly stop outputting the content of the page.

None of the code was changed and the site was working flawlessly prior to running the mentioned ssh command.

I do use output buffering in the site, but after removing the calls "ob_flush", "ob_end_flush" and "ob_start" it didn't appear to help—still having issues with the site.

Any ideas what this could be?

Here is output from terminal:
