In the ACT_config.php file, we have provided a default location for your working directory. It is: /opt/viewer_jobs. You can have to provide the correct access by :

#  chmod 777 /opt/viewer_jobs

You are free to create your own working directory.

First, in the root of your ACT Web Client directory edit the ACT_config.php file. Change the working_directory to the path and directory name you plan on usingrunning the chmod command as shown.

return array(
         'shrine_url' => 'your_SHRINE_URL_here',
         'working_directory' => '/opt/viewer_jobs',
         'site_name' => 'your_site_name',
         'debug_logging' => false,
             'shrine_connector_logging' => false
         );

Second, create the directory with correct access settings:

# mkdir /opt/viewer_jobs
# chmod -R a+w /opt/viewer_jobs
