Hi Bill,
Don’t worry, we will figure it out in no time.
After a quick look on the front-end, I noticed, that there is a results shorcode placed into an invisible mobile menu container – which is present on the page, but not visible.
The results are basically propagated to that container, but because it’s invisible, it appears as if the search was not working.
I can’t exactly pinpoint the of the shortcode, but it’s within a custom HTML block in a mobile only menu container in the header. If you remove that, then everything will work as normal again.
