Chris D, I found out why I reported some of these "oops" messages. My style does not display some elements, so all I got was the "oops" without the explanation-div.
In this case, I have just clicked on "search" without adding any search terms. The result was:
"Oops! We ran into some problems.
Please specify a search query or the name of a member."
Still, my suggestion is to remove the Oops Headline and just show the "Please specify ..."-helpful line.
