Issue

My application needs to write files to a directory on my site, but I am receiving an error when it tries to do this.

Solution

The default permissions on your directory structure enables read access only to your application. You can change the permissions on directories using the Plesk Server Administrator. The following steps can be used:

1. Login to the Plesk Server Administrator.
2. Select the domain name you wish to change the permissions on.
3. Click on the 'Web Directories' button
4. Next to the directory you wish to change the permission on click on the yellow padlock icon
5. On the Access Permissions page click on the 'Plesk IIS User' and 'Plesk WP User' and allow 'Modify' access for each user.
6. Click 'OK' to save these changes.
