With all the changes in it, I have been accommodating Ultimatum Theme 2.7.2 (a bug fix version, with another expected in the next few days). First up was providing a ‘sticky’ top menu, courtesy of a plugin called Sticky Menu (or Anything!) on Scroll. The trouble is, it does not work nicely with the UberMenu plugin I was using. Ultimatum 2.7.2 has a Bootstrap menu option. Using this, in the default position, with search showing, works well. Goodbye UberMenu, its associated additional plugins, and the code to load its revised stylesheet.
Also, I noticed that the EU Cookie plugin, which gives new visitors a warning about cookie use (stupid EU legislation), does not work with Ultimatum Theme 2.7 onwards, so I replaced it with (the nicer) Cookie Notice plugin. A number of other plugins have gone too, plus quite a bit of the custom code in the child theme functions.php file. It’s looking good.
One part of Ultimatum Theme that does not appear to have been updated, nor does it look like it will be soon, is WooCommerce Connect. Here’s hoping for the future of that feature.
