The message "Error running style: Died in S2::run_code running FriendsPage::print(): Style code didn't finish running in a timely fashion. Possible causes:Infinite loop in style or layer" means that the S2 Style on your Friends page could not completely load. This could be a problem with your Style code, but may also indicate that LiveJournal servers are too busy to process the style. Please try reloading the page. If this persists, you may wish to check over your Style code for errors or to open a Support Request.
I think it should go either before the paragraph about caching or afterwards.
