I have a bit of a weird thing happen since I upgraded to the latest version, my dropdown boxes like up by the username and login etc don't drop down any more, I'm just booted to a standard page for login - any ideas?
Does this happen when you use the default style? Can you select it from the AdminCP and try it?
Using FF, I tried clicking on the Quick Nav Dropdown, both for the top breadcrumb and bottom one. Nothing pops open, and if you do both, your site locks up. I compared your JS versions, and code, against mine and they are both the same. You can try reuploading the JS directory (yourXenForoPackage/upload/js/), to be sure. Have you tried disabling additional JS that you may have installed, or placed in a template?
Thank guys, you sorted my problem. It was the mailchimp stuff that I added into the sidebar. I didn't think it would have affected it. I will just add a simple picture and link it to mailchimp instead. That's what I love about this place, ask a question and someone answers it!
