No sorry. It looks like there are some problems with the minify function as this thread is also reporting other issues. Looks like it could be related.

Hi, I also have that issue.
Just posed a little before you. Thread here:

Hopefully there is something simple to fix it. I wonder if it was something to do with the last update. I noticed they changed the main index file slightly.
