Unable to Access Page
The value of the "icid" parameter contains a character that is not allowed or the value exceeds the maximum allowed length. Remove the character from the parameter value or reduce the value length and resubmit. If the error still persists, report it to our Customer Support team. Provide the URL of the page you were requesting as well as any other related information.
I'm getting this error when trying to log in to SFDC. Anyone have any ideas of what might be causing it or how to fix it? Otherwise I'm imagining a few days before I get a response from SFDC support.
