Thanks for the great plugin. However I have a problem.
I have two WordPress sites using the same theme, but on different servers.
I have installed Hyper-cache on both sites with identical settings. On one site hyper-cache works beautifully, in the other site only one .dat file appears in the wp-content/cache/hyper-cache/ directory, and then nothing else happens, except sometimes an empty _archive.dat file also appears.
Any ideas what the problem could be
