Last version works OK for me, older ones didn't

The plugin makes all my admin pages go blank as soon as it is activated, and the only solution I’ve found so far is to manually delete it (using FTP). Also, there is apparently no support in the forum.

I have the feeling that the plugin (probably) places too much stress on the server, at least in my particular case.

EDIT:

I want to be fair and correct my previous comment:

After my bad previous experience I decided to give it another try, and installed the last version (1.9.2). This version works correctly in my site – or, at least, does not give me the problems that a previous one did, and that I mentioned in my other message.
