In our wp-content/cache directory, we get a lot (and I mean a lot) of .tmp files.
It seems they have a random name, like this:
In a day, we can find thousands of these files. They are all stored in the /cache directory, not in /cache/supercache. It's a problem, because the folder become very huge if I don't manually delete these files.
I tried to switch to php or rewrite method, it doesn't solve the problem.
Is there anyone who can share an advice about this problem?
Note that we define the /wp-content folder to be a /custom-content (I do not think this is an issue, but FYI).
