Been getting this error for a few days now when using google search...... http://cse.google.com/cse?sitesearch=http://www.motoringalliance.com&hl=en&domains=http://www.motoringalliance.com&ie=ISO-8859-1&q=speaker+replacement&siteurl=www.motoringalliance.com/forums/usercp.php%23axzz2vz7g5Vdg&ref=
Google made a change a few months back. The plugin for Google Search is from 2008 and has not been updated by the author. I've been searching for some time as to how to fix it. Being as no one had said anything I wasn't in a rush thinking that few people actually used it. The important part of the message is "Requests without cx/cref are no longer supported" There are lots of other forums with the same error. Google's own Support Forums are of no help in the matter. Believe you me, I've looked.
Just the opposite for me. I never bother with the Google search because I like the default quick search. If quick search doesn't work for me, advanced search does. Still, it always sucks when a favored site feature stops working but that's the way it goes when those who develop don't continue to update and support.
