I just upgraded from 9.03 to 10.11 and am having a few problems. Most notably, there are certain features that are not working. Look at the menu above on the forum you're now on... When you hold your mouse over the "FAQ" or "Chat" links, you'll see an underline like you do most other links. However, when you hold your mouse over the "Search" or "Events" links, you do not see a link. There's a reason I'm bringing this to your attention...
On my forum, which was just upgraded, all the links that do not have underlines, "Search", "Rate Topic", "Topic Search", "Moderator Tools", "Topic Options", "Post Options", "Thanks", etc... Nothing happens when you click on them.
When I look at my JavaScript console, I see an error message that says "Uncaught ReferenceError: getAjaxData is not defined - forum_posts.asp: 428" when the page is loaded, then another that says "Uncaught ReferenceError: showDropDown is not defined - undefined:1" when any of these links are clicked on.
I'm sure it's a conflict somewhere, since it seems to work on other forums, like this one, but I have no idea what to do to make it work on my own. Any thoughts?
