I have turned off Ifinity URL Master and using the core provider in DNN 7.4.0
It now uses "userid" to pass around the UserId in the URL. In my old site this was settable against the profile page and I had it as "id". So now I have a lot of hardcoded links that use "ID" which are not working.
I need to tell all URLs with "id" in it to be rewritten as "userid" OR I need to tell the profile page to accept "id" or "userid"
