According to my host, my installed version of Podpress is causing some kind of problems where too many calls are being made to my server. They are not giving me any other tech details (otherwise I'd share) and I'm skeptical that it's actually Podpress causing the issue---which results in causing the server to lock up.
They say, "Your site makesocialmediasell.com was being hit extremely hard with traffic which was causing the server to lock up."
... and that they narrowed down the issue to my Podcast plugin. Does this sound familiar or is there a known issue? (I'm running 22.214.171.124)
