I have been trying to change the agreement of my phpbb fully modded board. I have followed what it said on the userguide (http://phpbbfm.net/support/docs/customize.html) . When i have edited the script as shown using Dreamweaver CS3 and uploaded it writing over the old file. When i try to access the board, it is going completely blank and nothing is loading. I would be really greateful if you can help me sort this out THANKS
