If the Advanced Settings are saved before any other IPsec is set up then $config['ipsec'] can be just the empty string. As a result you can get: a) If you select some debug settings then those are not saved. The code to save those settings was only executed when $config['ipsec'] was already an array. Actually the code already did the necessary "if isset() then unset()" stuuf. So I just took the the "if is_array()" away from the code block. b) Some potential unset() can go wrong with errors like: Fatal error: Cannot unset string offsets in /usr/local/www/vpn_ipsec_settings.php on line 168 This is corrected by adding more "if (isset())" checks. Fixes Redmine #4865

Actually the code already did the necessary "if isset() then unset()" stuff. So I just took the the "if is_array()" away from the code block and it saves fine the first time.
b) Some potential unset() can go wrong with errors like:
Fatal error: Cannot unset string offsets in /usr/local/www/vpn_ipsec_settings.php on line 168
This is corrected by adding more "if (isset())" checks.
