Wiki pages that I created in Seafile versions prior to 7.1 can no longer be opened. The MD file is still available in the library, but calling it using the Published Libraries function only results in the error message “We’re sorry, but the requested page was not found.”
Example link: https: //www.domain.tld/group/19/wiki/wiki-grundsatz
However, group 19 still exists.
I suspect the problem has been present since I installed version 7.1.5. Before that I was using 7.0.5.
