I have only tested the plugin on PHP 5.2 and higher, and there are a couple of required functions that only exists in 5.2 and up. I have implemented support for the internal WP object cache, but have not fully tested it myself.

Is it possible for you to test in another environment with PHP 5.2 with object caching turned off?

There was someone else a while back that was having a similar problem, but he did not follow up on the testing so not sure exactly what is going on.
