Great, thanks much, the footer is sorted now.
There remains one change caused by WX 5 that I haven’t been able to remediate. The search box is tiny and I can’t find the classes / ids to affect its formatting. Comparison here. Using the web inspector I found the classes / ids shown below, but they don’t control how the search box is displayed.
#search-3.widget, #search-form-1, .search-field {
background-color: #e7e8e8; line-height: 1.2em !important;
