Ok, I found it.
The W3 Total cache plugin was the problem. In the general settings I disabled Minify and everything all popped back into place. I am not sure of the reason but I am not willing to spend too much time figuring it out.
Thank you for your help Andrew.
Thanks for the speedy reply. Changing the display function does put the nav back on the mobile site. There are 2 issues though.
1. I didn’t modify any of the mobile CSS at all and the nav was displayed before. I checked in the original download of the theme and display is set to none.
2. The previous nav was a drop down selection (iphone style), now each page link is listed.
I can live with it but I would prefer having the drop down as before.
I really appreciate your help with this.
