Last week, my copy of CDpedia 5.3.1 lost its ability to search Discogs (designated as the primary / first site in the "Sites" preferences tab). No matter what text goes in the search box, the response is always "There are no matches for XYZ. Please try another search."
It worked one day, and then suddenly it did not -- and it still does not, a week later. I changed no settings or prefs before the loss of search capacity. Today I unchecked all sites in the Sites tab, closed the Prefs pane, closed the app, then re-launched CDpedia and restored Discogs as the first Site in the list. Still nothing.
I'm stumped.
