- Plesk for Linux
File upload via Seafile interface fails with:
PLESK_INFO: Unknown error
When opening Seafile storage in the Plesk Premium Email webmail, one of the following error messages appear:
PLESK_INFO: Authentication failed for seafile storage
PLESK_INFO: User credentials not provided
The following error is displayed in the menu Plesk Premium Email > example.com > Troubleshooting:
PLESK_WARN: Preferred domain redirects are not supported and will break various features.
This is a Seafile limitation - it may not work correctly when the website is using www redirection (configured in Plesk at Domains > example.com > Hosting Settings).
It will be resolved on future Seafile updates.
The next version of the Plesk Premium Email extension will warn about this limitation.
Go to Domains > example.com > Hosting & DNS > Hosting Settings.
Set the Preferred domain to None and click OK or Apply at the bottom of the page to apply the change.
