Hi. You might try the latest version, v1.2. I have this running fine on my site. I'm not sure why you didn't download the latest version?

I didn't write 1.1a, nor do I use it, so I can't help much there. You can remove it using the uninstall sql script from 1.2. Remember to replace all the files as well.

If you experience any blank parts with 1.2, use this tool and get back to me.
