It used to show at this site but not anymore, maybe it is a WPMU 2.8.1/BP 1.0.3 issue.
Anyways, even though there are many people interested in a working FB connect plugin, nobodys interested in developing it.
Hm.. strange. i noticed this button doesnt appear on wwpmu2.8.6/bp1.1.3 too (bp-fbconnect plugin).
oppss.. just found out this is due to fbconnect.init not called in the footer.
@af3 — what do you mean? I’m having the same issue with the button not appearing on /wp-admin.php, but the only instructions say to use <?php do_action(‘fbc_display_login_button’) ?>.
Bizarrely, the button will occasionally show up when someone logs out, but I can’t get it to appear with any regularity. Using that code in a template works just fine, but not on /wp-admin.php.
How did you fix it with fbconnect.init in the footer?
For me the problem was that “php wp_footer();” was missing from my footer.php file. Once I inserted it the button reappeared. Hope this is a help to someone.
