since moving to a host using LiteSpeed, we've started having a problem with W3TC, with a blank page showing instead of our site (it's not the "blank page at dashboard" issue).
After disabling and enabling plugins and features, I've noticed that the problem was with CDN at W3TC: if disabled, the site loaded ok; if enabled, we had a blank screen.
With the help of our host, we've concluded that the problem was with eAccelerator (v. 0.9.5.3), and we've had to add the below to our .htaccess:
php_flag eaccelerator.enable 0 php_flag eaccelerator.optimizer 0
With this, the site loads perfectly and we can use the CDN feature on W3TC (Rackspace).
I had the hope that this would be unnecessary with the latest update of W3TC, but I've noticed that it's still there.
Is there any different workaround for this?
