I thought your plugin would help to boost my wp 3.2.2 and bb 1.5.5 site. but it does not. It's faster without your caching module. In combination with zend otimizer my site works faster without any errors.
But I'm very unhappy about the situation as I reseted and deactivated the plugin. This way deleted the
<?php ?> command in my wp-config.php. I needed some time to find this error.
Now my site works fine again but your plugin is to dangerous for a nice handling, sorry for this commentary.
