Thread:Project:Support desk/Vector skin fails to style intermittently/reply

You have a similar problem that I'm working on. My system is ubuntu server 11.04 running just like your setup with slightly more extentions. My problem is that when I try to look up the pages it does not style intermittently however when I try it on my lan (same setting and everything) it works perfectly 100% of the time. So I used Yslow and it appears that the error is caused by a failure due to load.php. I am still not sure how to remedy it atm.
