For the life of me I can’t get the search bar styles to apply in the sticky header. Any ideas? Would really appreciate it if you could look at this today. I was supposed to present yesterday but then some plugin updates variously fucked things up (not yours, but yours was affected somehow).
Thanks for the details. I have changed back the CSS compatibility level to the optimal here: https://i.imgur.com/7k4lWQd.png
Now it should be all right. The other option had some rules that did not work properly in this case.
