cURL error 28:

Hi!
I could solve it with this code

<?php
//For PHP 5.x
session_start();

session_write_close();
?>

Is the error related to the plugin? Which file did you add your fix?

Hi. Yes. Because when I activate the plugin this error appears.
I added it in fuction.php and it disappeared.
However, the cron that automatically sends the emails is not working (or even copying the url in the bar or with the server) any suggestions?
The cron every 1 hour does work.
