DirectAdmin Can't Save Plugin Configuration
If after installing the Bacula4Hosts Directadmin plugin via ssh, you are having issues with the plugin configuration form in the directadmin web interface, there are two places to check first:
1) Ensure php safe mode is disabled in your PHP build
2) Php exec functions are disabled
If you are not able to accomodate these requirements, you may be able to update the php configuration as options after #!/usr/local/bin/php at the begging every script.
