Thanks a lot! Yes, this worked for me.
By the way, I am running the site on a Windows Server 2008 (WIMP).
Here is what to do:
Go to your WordPress dashboard and select “Settings” (at bottom on the left).
Then click “WP to Twitter”.
Now, the easiest way is to search for “HTTPS”. You should find a section called “Disable Error Messages”. In that section is a checkbox with “Switch to http connection. (Default https)”. CHECK THIS. Then, check “Save Advanced WP->Twitter Options.
You should be good to go.
