Upgrading to 7.1.3 - "Error" in web interface

Ubuntu/linux install

Just a quick note to anyone who is upgrading and just sees a generic ‘Error’ message when loading the web interface.

Make sure your ‘seafile-pro-server-7.1.3’ folder is owned by user ‘seafile’.

I had extracted the tar.gz file as root, so all the files were owned by root, and group root. simply doing a chown and chgrp solved the issue.
