here's my problem:
with Super Cache enabled, the home page of my site sometimes gets completely blank. I can't find what triggers this behavior, it may happen twice a day, sometimes more than that. When this thing happens, the rest of the blog is loading super correctly and in a very fast way. The problem is limited to the home page.
If I turn OFF Super Cache (not disabling the plugin, just selecting OFF from the panel) the home page goes a little nuts. It loads again but it stops before loading the sidebars and the footer.
Here's the way I solve the problem (but it doesn't prevent the problem from happening again, obviously):
I log into my server administration panel (The site is on a dedicated server) and I restart the Apache webserver. After that, it's all back to normal.
Sometimes when I restart just after discovering the blank page, with Wp-SuperCache still ON, the Apache restart isn't enough and the white page persists.
In that case i Turn OFF Wp Super Cache (the home page goes nuts) I restart Apache, (the site goes back to normal) and then I turn Wp Super Cache ON again.
So, someone has a hint of what's going on here?
