# Question not visible from certain computers

This sounds strange: when I go to the webpage The units of $\mathbb Z[\sqrt{2}]$, in the right pane, under "Linked", there is a link to the webpage Determine all units of the domain $\mathbb{Z}[\sqrt{2}]$ which is the question I posted. Clicking on this link when I use my laptop takes me to the linked page correctly, but when I use my desktop PC or iPad, clicking on this link keeps me at this same page. Why does this problem occur? Also, for my reference, I wonder if this linked page can be made visible from all PCs, including from my profile.
