I have decided to pay for new VPS, setup webpanel and then migrate all to the new server. Later on, when everything is done just cancel current VPS.
Thanks for answering
I have made mistake and I install WP before Froxlore. Using this example http://sliskovic.online/install-froxlor-centos7/
Now my question is; how to "import" this site into Froxlor ? Can I just copy all files into default site structure?
