I tried to install simple press on Multisite at URL http://coupondelhi.in/forums. After installation when I hit “Go to Forum Admin” button I got the following error.
“You do not have sufficient permissions to access this page.”
After that I found Simplepress was not installed as I had install option once again. So, I tried to install again, but I got same result.
WordPress Version is 4.4.2
Simple:Press | Version 5.6.3.1
