I have a user who is going to the website with : https://www.ourwebsite.com adn after she gets to the admin section and looks up an item she gets a server error msg and will have to close the browser window then she gets the "certificate untrusted" error message. We have deleted the cert8.db we have cleared the cache, history and cookies, we have reset firefox, & nothing seems to fix the issue, PLEASE HELP, she is the only person getting this message, and it only happens when she connects her laptop to the network at the office. It doesn't happen at her home, it doesn't happen over wifi? PLEASE HELP!
