I am using SMF 1.1.13 with Ezportal. I created a page that is membergroup specific and when someone outside clicks on the page they are directed to a page that says, "An Error Has Occurred! You do not have permission to access this page." I want to customize this page to have my own error message, but I don't know where the page file is located and I can't find it. If anyone does know this please help me out. The end of the address of the page is: /index.php?action=ezportal;sa=page;p=1

I was looking everywhere, but the right place. Thank you so much!
