Factor in from that huge list, the developers who no longer provide support, can’t be contacted or no longer have anythng to do with Rapidweaver and conflicting versions or JS as well as duplicated font and icon files, and you have a heady mixture of potential problems.
@kent you actually reported a very similar issue just 1 day ago in that you added a stack from 1 developer that broke your site. You were lucky that the developer had the incentive to find the issue and fix it.
