I also tried to go to your site a moment ago because I had to delete the plugin. I was thinking maybe the problem I saw the other day was fixed. Unfortunately the problem I saw the other day was the timthumb.php had been compromised. I used the Timthumb scannner and for the first time it was picked up on this pluggin. Now a moment ago I went to your site and it told me the same as bundyS saw. I do hope you can correct both issues. There is no other shortcode plugin that can compare to this one.
Please fix.
