For further understanding, when said recently upgraded to 1.5.8, is that to the base version of 1.5.8, 1.5.8a, or whatever changes had been made to that version after the release of 1.5.8a?

I don't want to go evaluate an updated base site to find that the issue had been addressed in a yet applied version. I also know that I haven't deeply inspected the main page rearrangement of 1.5.8; however, historically the footer often was made in some way different on non desktops though not usually to become a side box.

As far as the issue occurring on a tablet itself, any indication of whether the issue occurs in portrait or landscape view? Both?
