Can't access site with my ip

I’ve even added the whitelist function:

function my_ip_whitelist($allow, $ip) {
return ($ip == ‘my ip #’) ? true : $allow;
}
add_filter(‘limit_login_whitelist_ip’, ‘my_ip_whitelist’, 10, 2);

But still can’t access the site.

I’m testing on a Mac.

But the problem seems to be when I view the site on firefox or chrome I get a denied access page.

But it works for Opera and Safari. Not sure why this is happening. There are Browser issues with this plugin.
