Can I add JFBConnect login to default joomla login

I have been using JFBConnect successfully for some time, and have the 'login with Facebook' link added to the log-in page that is linked to from the main menu on my joomla site (jooma 1.7). However, access one resource on my website is restricted to registered users, and if the link to this restricted resource is followed then joomla brings up the default login page which only includes joomla login. Does anyone know what code I need to edit to add 'Login with Facebook link' to the default login page that is shown when trying to access restricted content (when not already logged in)? I don't seem to be able to find a module that is controlling the log-in screen that is brought up automatically when attempting to access restricted content? Any advice would be greatly appreciated.

Hi Alex, this one has got me stumped somewhat! I have tried to add the {JFBCLogin} tag to various locations within the file you highlighted, but I'm not getting the "Login with Facebook" button to appear. Is there some where specific it should be added (php below)? Was trying to get it to appear below the joomla "Log in" button. Any further suggestions would be welcomed. Thanks, Justin

Interestingly, nothing is appearing on the login page.... neither the "TEST TEST" or the facebook login button. I did clear both the joomla cache and browser cache when testing. Would seem that we're not editing the correct bit of code (or file), rather than a failure of the {JFBCLogin} tag.

Alex, I have solved the problem. Your solution works just fine. Why it wasn't working is that I use a Yootheme template, which points to a duplicate default_login.php stored under the Yootheme template folder! Alas, once I discovered this and edited the active version of the default_login.php it worked! Many thanks for all you help. p.s. I need to renew my subscription.... can I do this before it runs out in about 5 days, or do I have to wait until it expires then renew?
