Do not uppgrade to 1.5 Jobroller
I am not saying the theme is bad or good. I am saying i been around the forum and seen many serious issues like, it not showing in IE. A patch should come sooner than later and all you that have child theme need to upgrade again.
Just my personal view feel free to upgrade if you wish but from what i seen on the forum the reactions are not that great and when more than a few people have same issue a patch need to come.
