I’m a little confused… are there two questions? It seems like the category filter is not working and you want to change the “Search” string in the keyword search input. Is that correct?
The first issue of the category filter not working, can you share a link to the page with the issue so I can see?
Here are the settings to change the “Search” string in Say What?
– Original String:
– Text Domain:
– Text Context: blank
– Replacement String: Whatever you wish it to say.
I hope this helps, let me know.
