OK, because of a previous post I did a 'mouse over-make visible-" click on the page and layer gallery and this came up. It is on the variant home landing page.

Could this be the issue?

One is a record document made by the previous builder (link to file log.xara Change. Remove.) for record keeping, the 2nd is a text Heading info. I doubt the log.xara has anything to do with the issue as the About Us page has the same item and the mobile page displays normally. However, these are not visible until the "mouse over" make visible is clicked.

Can the Heading info be the culprit, or not?
