Using the most recent version and I've been getting premature end of script header errors that have repeatedly crashed my site when adding new posts.
As part of that, I went on a debug mission and while I'm not sure if this was the culprit, it could potentially cause those errors. Both PHP files in your plugin have an extra line of space at the end of the file. I removed it on my site and we'll see if it makes a difference. Just wanted to give you a heads up.
