I'm having regular "CPU exceeded" errors from my host. I'm also getting occasional "site not found" timeouts.
The host has advised that the problem lies with my index.php file (I haven't amended this at all - it's the default installed file). They've also suggested I switch off any plugins.
I've switched off most of the plugins I was running. All that's left is:
Angsuman's Translator Plugin Pro
Feedburner Feed Replacement
Google Search Widget
WordPress Database Backup (set to backup daily)
None of these (to me) look as if they'd use significant CPU time to execute. Traffic on my site is very light - maybe 20 visitors per day.
I've tried running WP-Cache, but that didn't help.
I'm using the Typo XP Reloaded theme.
Can anyone help, please? This all started quite recently - my site was fine for a few weeks before now.
