On my phone, the navigation menu doesn’t work, and on my laptop, I can’t see the navigation menu. I’m using Rapidweaver 8’s Mountains theme at http://secondlanguagewriting.com/slwis/
The first thing to check is that you have “Show in Navigation” selected on your pages. I’ve never used that theme so I can’t be much more help than that.
Thanks. That was it. I didn’t imagine that when I switched from 7 to 8 and at the same time to a new them, the navigation would drop out. The strange thing, which was noted in a different post, is that the mobile navigation is behind the title on the banner, which can obscure some links.
