This Website “Search” Inoperative?

It seems the “search” function for the entire www.ads-software.com website (and forums) has been inoperative for the past two days.

The search box accepts a search term (e.g., “WHERE”), but the rendered page displays only header, footer (i.e., https://www.ads-software.com/search/WHERE+intext%3A%22Plugin%3A+Pods+-+Custom+Content+Types+and+Fields%22/?in=support_forums), but with nothing displayed in the page body (and no error message).

I’ve tried four different browsers over two days (using Windows 10, rebooted) with identical results. Being logged in or not does not affect the problem.

Anyone experience this or have any suggestions how to proceed with the search function?
