Hello @una102 !

If you don't have the possibility to setup SSL on your site, then you need to edit the inc/header.inc.php file of your installed UNA and correct the value of the BX_DOL_URL_ROOT constant to use the http instead of https like:

from:

define('BX_DOL_URL_ROOT', 'https://una.nicodemusventures.org/'); ///< site url

to this one:

define('BX_DOL_URL_ROOT', 'http://una.nicodemusventures.org/'); ///< site url

BTW - the key-secret should be set up for the http://una.nicodemusventures.org/ domain too.
