File upload via Seafile interface fails with:
PLESK_INFO: Unknown error
When opening Seafile storage in Plesk Premium Email, 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 Plesk Premium Email > example.com > Troubleshooting:
PLESK_WARN: Preferred domain redirects are not supported and will break various features.
This is a Seafile limitation, the extension 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 Kolab extension will warn about this limitation.
Set Preferred domain to None in Plesk at Domains > example.com > Hosting Settings
