Which webhost are you on? How many members are registered in your site? If multisite install, how many user blogs do you have now? Basically, It means you need to upgrade your hosting plan to VPS and the like.
I am with hostgator and I have a reseller account. I have 47 user blogs and about 1000 posts.
I installed wp-super-cache and it broke all links to the buddypress pages.
I asked them about that and they suggested I go for a dedicated server.
With about 20 000 visits a month for 2 sites I find it a bit ridiculous.
Should I deactivate buddypress before I install wp-super-cache?
A reseller account gets the same resources and limitations that shared hosting accounts are allocated. They both cough in the same boat and same environment. What about a VPS?
A VPS would be fine but now only the front page loads properly. All the others give a 404 error
Pretty permalinks are required for BuddyPress sites.
Settings > Permalinks and choose option other than default permalink.
