I can’t get the YARPP plugin to work. I’m running WP 2.8 and 3.0.6. Just upgraded both WP and the plugin yesterday, which is when it stopped working. It worked great before. The server is running PHP5 and MySQL 5.0.45.

I read through the FAQ and the forums to try and figure out what’s going on, but still can’t get it working. When I re-build the cache, then return to the YARPP options page, it shows the cache at 0%. The build on the fly option is enabled.

Any help would be appreciated.
