You are want to log in to Lotus Notes with Chrome/Firefox. When you type " lotusnotes.k12.hi.us ", you get directed to a page that has the keywords "Blocked," "Warning," "Error," or anything other than the lotus notes login screen.
Many people experience this problem. One solution that helps is to type " https://lotusnotes.k12.hi.us " on the address bar on the top. For now, we aren't unsure as to why it directs you to a said blocked or unsafe site, but we do know that the " https:// " is important to type when you are going on the lotus notes website.
