Comments error when you are using https??
If your are using SSL on your website and you have problem with post comments , Ajax Error 302.
Then please add this code in your functions.php file.
add_filter('option_siteurl', 'convert_https');
add_filter('option_home', 'convert_https');
function convert_https($text) {
return str_replace("http://", "https://", $text);
}
Thanks
