I used my normal link to go to the forum to find it has been corrupted .
Tried on google chrome and firefox , both go to the same place . tried going via search engine search results , and came up with the same thing
Went to Internet Explorer , which i rarely use , and found the link tthrough there still worked OK ..Copied and pasted the IE link to the other browsers and it works ok there .
I have left a message for joe at facebook about the problem ,So he can look in to it .
Here is the link i used .
