This is frustrating for me.
I have the latest wp in both.
domain.com/blog - is a separate installation and the main blog
domain.com - is a separate installation with buddypress
domain.com/blog - is using Wp-Super-Cache for caching posts etc
domain.com - is using W3 Total Cache excluding pages for caching activity
Every day one or the other site's permalinks do NOT work, and I have to re-save the Options/Permalinks ... I usually just do both - then the permalink posts work fine.
I'm in the process of setting up the buddypress site and tweaking stage . yet, according to my WHM since I've done that my CPU resources jumped from 49% to 74% ... This week I did the same thing to another domain and setup a buddypress site - but in a folder, not the root - and the permalinks work fine. The CPU Resources jumped from 74% to 89% and fluctuates now between 70-90% all the time. There are not many people on my site at a time .. maybe 9? 10? 35 at most?
Is there any recommendation for getting this caching under control and redirection? I can't even access my blog right now because of it .... http://PetLvr.com/blog/
