Website Write Permissions allows or disallows your web applications from having the ability to write data to the server. Write permissions should be enabled for every domain by default. You may change this setting for a particular domain by following these steps. First, log into your HELM control panel. Click on Domains and select the domain name from the list. Next, click on the Website Settings icon. Check the box next to Website Write Permissions to enable or disable write permissions for your domain.
