Library error to access by owner

I have two libraries, shared and that are being synchronized between the users in which they are shared, the problem is that the owner of the two libraries can only access one of them in the web interface a blank window comes out, without options it is not that is empty, because users who have this shared library are still working, the client says server error and in log says Bad response code for GET 500
