AS Jason says, I don’t think there is a need.. APC for me during my tests, is still the fastest method I’ve found to a quick loading website. I’ve outlined my whole configuration here, http://boi-infinity.com/wordpress-optimization-2014-behind-boi-infintity/
As I had mentioned, it was a permission issue. Sometime on certain systems when u auto upgrade, you inherit the settings from the developer machine. Your host should read, http://www.wikipedia.org/wiki/Chown as it would have solved your problem in 5 seconds.
A quick hack for this is to open up your template header file.. You’ll see code that looks like
<a href="<?php echo get_settings('home'); ?>/">home</a>
Just remove the home from the link code..
EG:
<a href="<?php echo get_settings('home'); ?>/"></a>
Now, create a new static page called home, go to the options / misc and set Front Page to Static and choose home from the dropdown.
