That page is index.html in your main directory. .html files are displayed before .php so simply delete index.html and the problem should be solved
The website is loading fine for me.
However, you are only allowed to have one .frih.net subdomain(and for a change you need to request it).
I am sorry. I was not aware of this fact.
Why is it possible to make a domain when you are not allowed to?
DirectAdmin isn't made by us and there is no option to prevent this.
