Hi,
Thank you very much for the details, it helps us a lot!
The issue here is the actual results page, not specifically the plugin. When I try for example the “cathedral baxter” keywords, I can see the result on the live results list, here: https://i.imgur.com/YO7QJi4.png
When clicking on the magnifier or hitting the return button, the plugin redirects to the results page, and “instructs” wordpress core to show these same exact results there. There is however a custom search results page present on your installation, which shows it’s own results, via it’s own query, with a custom tab feature of some sort. It seems like it does not use the wordpress search results, but does a separate search query on it’s own, and then display it’s own results. Unfortunately that is the problem. While the plugin does the search override, this custom results page/plugin does it as wel.
