The seach and filter plugin works fine except for one hiccup.
The JavaScript category is not found ??? I checked the pages with the JavaScript categories, they are ON. See attached printscreens.
It is excluded, because the item is also in the PHP category, which is unchecked in the filter. I recommend changing this option like so: https://i.imgur.com/yUgCIl1.png
It will change the logic, so that the unchecked boxes are not treated as exceptions.
It looks like it’s caused by a 3rd party shortcode, when trying to get the content. Please switch back this option to the default: https://i.imgur.com/YEbzyaR.png
