Super Cache works great much of the time, but unfortunately something seems to happen to it when you approve comments on my system. It just stops working. It seems that it partly or mostly clears the cache upon comment approval. And then it doesn't create any more cache files.
The solution seems to be the manually delete the cache every time I approve comments. Then, new cache files are quicly created and al is well. However, this is klugey and if I forget to do it, my server quickly gets overwhelmed because caching has effectively turned itself off.
I would be able to load a lot more "stuff" into my WP installation if I could get Super Cache to work more consistently. Right now it's delicate because of the way it stops working periodically. If anyone has any ideas, I'd love to hear them.
