So, I've got a bit of a bizarre issue. Admittedly, it's probably because the site wasn't built with DNN best practices in the first place, but the shop I'm at had never used DNN before when they built the site and we haven't used it since either. So, literally this one client is the only client that has a DNN website for us. Well, some functionality they want made looking like updating from 7 to 9 look reasonable. So I've updated the development testing site to 9, as a way to prep for when I'm going to update the live site.

Here's the problem, it's now impossible to get to any admin area if you don't go directly to the URL. Like, /admin. The menu just doesn't show up correctly. Looks like a javascript issue, I'm betting something that DNN is expecting isn't getting loaded correctly. Depending on the page, I either get a "window.top.dnn.getVar is not a function" javascript error, or a "TypeError: Cannot read property 'value' of undefined." Both of these errors do not occur at all on the current live site, so I feel pretty confident in saying that the upgrade and the new menu are having issues. I can provide screenshots if necessary.
