Re: No remote access
What "black page" do you mean? How are your colleagues accessing your files?
No remote access
A colleague of mine has been unable to access my files despite I have allowed access. Attached how I activated remote access, which however doesn't work (instead of my files a black page is shown). Maybe do I have to update it?
