So I had a perfectly working Flarum for about a year, and then I changed the main domain of my box (without altering any files).
As far as I know this shouldn't do anything to my Flarum, but now nothing at all seems to work with it, and I get Error 403 on every single page (except index, which is blank).
How can I reset my forum and set it up from scratch (without deleting all the files and start again) because I have literally no clue how the install process works and I had to pay somebody to do it for me last time.
yours,
Rocky
