https redirect login problem

[pityocamptes]

In the back end I have this:

My forum url is : https://www.XXXXXXXXXXXXXXXXX

Home Page URL is: https://www.XXXXXXXXXXXx

Both are exact.

However, I noticed when I just put www.XXXXXXXXXXXXX in the browser it goes to my index page like normal. However, when I tried to login, I would get a redirect error.

I changed the forum url to: http://www.XXXXXXXXXXXXXXXXXXX

and it seems to work now, as far as logging in. Was this correct to do, should I do something else? Thanks!
