Sorry for the outage this afternoon. A PHP upgrade broke one of the plugins I used on our WordPress based website.
If you are using:
WP-Optimize - Clean, Compress, Cache (version 3.0.16)
On your website, you should remove it as it will break under our current environment. Also, testing with and without it, it no longer confers ANY improvement in load time, in fact our website loaded slightly faster without it.
