Vortex3929 That's something, least you can use the forum at this point!
There may be something in the theme which happens to be triggering some sort of error in a particular circumstance, but very hard to track that sort of thing down. There is an update due on the theme which I was going to put in tomorrow though, so I'll ping you in this thread when it's done. Never know, it may flush out whatever the issue is.
Out of interest, when did this start happening?
