This comment is related to this old thread on Softaculous.

My hosting company has the Softaculous Staging and Clone options available for Backdrop.  I tried setting up a staging site today, and when I attempted to view the staged site, received an error related to config files.  Is there something special that needs done to make a staging site "work" properly?

I've never used Softaculous, but I've seen this problem in my dev settings, when the config directory for a site is empty, but Backdrop database has already been installed. For example, when I want to reinstall Backdrop locally, and I remove the config directory, but forget to truncate the tables to do a new installation.  

The config>active directory has all the json files that were copied when Softaculous did the staging setup, so it isn't empty, and it does exist.  I've had problems moving/copying config files (when done the "wrong" way), but with the fatal error, don't have a way to log in and properly import the config files.

 

The config files in settings.php are set to this.  The error says to check the variable, but I don't know what the variables "should" be.  However, they appear to be the exact same settings in the site that is working:

$config_directories['active'] = 'files/config_' . md5($database) . '/active';
$config_directories['staging'] = 'files/config_' . md5($database) . '/staging';
