I've noticed that "language" and "sections" icons on the SOTT page don't work; they don't unfold.
Do you have such a problem on your computers, too?
If you're using any add-ons or extensions in your web browser, try disabling them to see if that's the cause. Depending on your settings, the fastest way to disable them may be to simply open an incognito/private window and see if the problem occurs there as well--if it doesn't, it's probably an extension.
Also, if you're using an old version of your preferred browser, try upgrading.
