[Koha] Koha Startup

Hi Nicole, Do you have advice on how I can open our koha at Science Leadership library (Philadelphia)? Some time in June a new contractor took over the server, which is located at the Franklin Institute, out of our control. Since then, I can't open the OPAC or do any circulation functions. When I try opening, it redirects from port 8000 back to port 80. But we think the port is open, because if you try to go to an unopened port, then you get an error message. warm regards, Paul Scaer, Librarian
