Oy. I can't find any of those tabs, either. It appears this is run on the php software or app platform, and a quick search sees many other forums having this issue too.
Long sh0t, but sometimes when I have issue like this I go to my browser's (Firefox) preferences page and click whatever I need to do to override what a given page does with my own preferences.
A workaround, for sure, but most often works. Worth a try.
