I found another issue. I need to fix the method for verifying authorized admins. The variable $admin_user_login with Cartpauj PM was associated this wise:

$adminOps = get_option('cartpaujPM_options');
$admin_user_login = $adminOps['admin_user_login'];

In Cartpauj PM there is only one admin so this is straightforward. But in Frontend PM you can have multiple authorized admins. So I need to develop a different procedure to verify authorized admins. I see you have a function “fep_get_option”. Can I use this to return an array of the ‘username’ entries for admins entered? If so how? With this array I can check if wp_authenticate($_REQUEST['login'] is in the array. That should work.
