Web GUI failing

[ronberlin]

After disabling IPSec via the Web GUI and saving the setting, the Web GUI is not accessible any more.
When I try to access the firewall I get this error

Code: [Select]

Warning: copy(/conf/config.xml): failed to open stream: Device not configured in /usr/local/opnsense/mvc/app/library/OPNsense/Core/Config.php on line 541 Fatal error: Uncaught OPNsense\Core\ConfigException: invalid config xml in /usr/local/opnsense/mvc/app/library/OPNsense/Core/Config.php:344 Stack trace: #0 /usr/local/opnsense/mvc/app/library/OPNsense/Core/Config.php(373): OPNsense\Core\Config->loadFromStream(Resource id #17) #1 /usr/local/opnsense/mvc/app/library/OPNsense/Core/Config.php(542): OPNsense\Core\Config->load() #2 /usr/local/opnsense/mvc/app/library/OPNsense/Core/Config.php(303): OPNsense\Core\Config->restoreBackup('/usr/local/etc/...') #3 /usr/local/opnsense/mvc/app/library/OPNsense/Core/Singleton.php(51): OPNsense\Core\Config->init() #4 /usr/local/opnsense/mvc/app/library/OPNsense/Core/Singleton.php(72): OPNsense\Core\Singleton->__construct() #5 /usr/local/etc/inc/config.inc(68): OPNsense\Core\Singleton::getInstance() #6 /usr/local/etc/inc/config.inc(314): parse_config() #7 /usr/local/www/guiconfig.inc(35): require_once('/usr/local/etc/...') #8 /usr/local/www/index.php(31): require_once('/usr/local/www/...') #9 {main} thrown in /usr/local/opnsense/mvc/app/library/OPNsense/Core/Config.php on line 344

Anyone else having this problem? How can I fix that (besides setting the firewall to factory defaults and upload the backup)?

Thank you very much in advance,
Ron
