Facebook Connect Redirection Loop

Hi all: When i try to use "Facebook Connect" to login o开发者_StackOverflown my website, i have the following problem:

If the application of my website is not added to facebook, i have to authorize it. Then I have a redirect loop in mozilla, chrome , but not in IE. If the application is added to facebook, works ok.

does anybody know why?

change your .htacces to default, like :

RewriteEngine on
RewriteCond $1 !^(index\.php|(.*)\.swf|assets|v1|images|flash|system|uploads|robots\.txt)
RewriteRule ^(.*)$ index.php/$1 [L]

i guess you have set the incorrect url in fb for the redirect, make sure all the app settings are correct on fb and give it some time to propagate
