I am also getting this same error. I have followed all of the steps in this thread including installing Wp Super Cache, and upping the Cache expiration time and lowering the cache cleaning factor. To no avail. The site is currently on a temporary URL, I will reenable debugging for the time being, thank you in advance @k2eric.
