Recently Roundcube has started logging me out so I have to keep on logging back in. The log in screen has changed and is now black; my first attempt often fails (no data) but works next time. I'd like to stay logged in, as I have done for years. Is this a Roundcube issue or Gridhost? Also Roundcube has become incredibly slow, particularly to load the Inbox. My version is 1.3.4. Any ideas?
