I seem to be having the same problem: “you need to authorize you Twitter accounts”.
username & password for twitter are correct, have the latest version of Twitter Widget Pro. I did not adjust any of the settings, this message suddenly appeared. Same response is given: “Could not recognize the response from Twitter”, when I type in the username & password again. At the affected site the twitter widget keeps on saying “loading tweets”.
I have absolutely no idea how to fix this, any suggestions anybody?
thanks in advance!
