No that is not what I mean. My forum url was https://www.preppers-shelter.nl/forumThat's not what XenPorta does... it doesn't change your base URL.
To install xenporta I had to move my forum to the domain root. After installing xenporta my forum was not reachable at the old url so I had to change that to https://www.preppers-shelter.nl/forums
With the extra S at the end.
but I understand the base URL needs to be something else? point not to the forum url but point to domain root?
