We've been LOVING this plugin. It must have increased our load time by 1000%.
However, lately we've been noticing a time out kind of issue when you publish or Save a post. The Post still gets published and saved, but it's telling me that I've lost connection. Then I have to refresh. We have a lot of contributors, so I don't want them to think they broke the site.
I would imagine that this is related to the cache plugin. Let me know what to inspect- I'd appreciate it.
