SymptomsYou have a domain hosted in Parallels Plesk Panel and you changed the FTP login details using the web control panel. After that, the website is asking for the user name and password. Also, the domain's file manager is not available.
CauseSome permissions were changed when the FTP user credentials were edited.
ResolutionThis problem was discovered in Parallels Plesk Panel version 18.104.22.168, and the fix will be included in future updates.
The hotfix is available and can be applied on the server. Replace the file "%plesk_bin%\usermng.exe" with the file from the attachment. Do not forget to back up the original file before applying the hotfix.
Use these instructions to set the permissions in such a way that the user can access the FTP location:
- Delete the ".security" file from the domain directory:
- Reconfigure the domain settings:
"%plesk_bin%\websrvmng.exe" --reconfigure-vhost --vhost-name=domain.tld
- Check permissions for the domain. Click the Domains shortcut in the navigation panel. Select the check-box corresponding to the domain name you want to perform the permissions check on. Click "Check permissions."
IMPORTANT: All custom permissions will be lost if you repair permissions via Parallels Plesk Panel. They should be restored manually. For details, refer to the article Repairing Access Permissions in the Parallels Plesk Control Panel 8.6 for Windows Administrator's Guide.
