I have two test portals, the essential difference, as far at Beta Testing is concerned, is one has Articles and one doesn't. On trying to check to see if some gremlins I have with the Menu Manager
were common to both, I tried to create some articles on the Fiddlers Elbow. I already have a couple of links to posts in the menu and can add to the menu OK, (with the correct on and off buttons) but the article only saves the title and not the article itself. I have no problem with this on my SGR test site.
One essential install difference may be that SGR is a clean install of 0.72 into a clean SMF, whereas the Fiddlers Elbow has been updated with all the beta versions since 0.65.
