Nethserver wordpress

Yesterday night I’ve followed a installation for nethserver wordpress this is what I did:

After that I typed: config setprop wordpress URL foldername signal-event nethserver-wordpress-update

I did not changed “foldername” into my URL, now I can’t log in to wordpress anymore and I don’t know how to fix this. Is it possible to unset/delete a property?

This is the site with the problem

It is, or you could just set it correctly. To delete it, you’d just run config delprop wordpress URL followed by signal-event nethserver-wordpress-update.
