We run a queer media website on wordpress. We just moved off of a dedicated server to [url removed, login to view] and are experiencing serious memory issues that are causing us to overload the server. I need someone to figure out what plugin, or theme file is causing the issue and fix it. We use w3 Total cache. We have a CDN set up. We have enough nodes to handle traffic, yet our site is either down or loading at an extremely slow speed.
