You need to install an SSL certificate if you want users to be able to connect to your site securely. The cpanel subdomain is issued a cert automatically but any of your own subdomains (as well as your base domain) are not. 
 

You can get a free certificate from a variety of providers, including LetsEncrypt and tinkerhost.net. 

I’m quite confused what are you telling us /asking us. The domain studenthosting.pp.ua works perfectly fine over both HTTP and HTTPS

If you add the domain to MOFH, users can create subdomains on it. If you don’t want them to do that, don’t add it to MOFH. 
 

Also, new users cannot signup with a MOFH-provided subdomain, they have to use of your subdomains. 
 

Lastly, users being able to create subdomains does not affect the speed of your website is any way. 

Yeah that is a very interesting error. Your file must be called “signup.php” and be located at the document root. If you’re using a MOFH template, don’t modify it. 

Download the latest version for GitHub and replace the current files on your website with the new ones. 

Yup

Your registrar is the company you bought your domain from. If you have a free subdomain, you don’t have a registrar and cannot change your namservers. 

He fine, living his (hopefully) best life

I wonder how to add SSL to my vista panel url as well?

You can’t. It should be done automatically. If it is not there in a few days, ask iFN.

Verify domain ownership via DNS record using CNAME

Did you add them in the vpanel account you were given for the domain? Refresh the page and make sure they are still there.

And what are the benefits of reseller API

You can create your own client area. See app.tinkerhost.net for an example. 
 

For setup, see the docs at

how to change the users prefix?

You can’t. 
 

if you add another domain to the account you will be able to set the prefix for that domain. You can’t set the prefix for the first domain, and the prefix cannot be changed after it is setup. 

Yes, there is a reactivate call. However, it only works for accounts suspended for inactivity, and should only be used if the user triggers it. 
 

as for the reset password, it does work. Check spam

What tells you to wait 60 minutes? What domain is the problem? You need to provide more info if you want help. 
 

and it can take 3 days for DNS to propagate. 

You need to add the CNAME record shown at the bottom of your screenshot. 

Request a certificate from GoGetSSL, the 90 day trial one. 

Your screenshot link is invalid. Also, can you explain your problem a different way? I am kind of confused. 

Disk space is not unlimited, it’s 5GB 

You need a link back to iFN

The about us page is a run-on sentence (And Softaculous should be capitalized)

you might want to add a login button to the top menu

on the flip side, it’s designed quite well for mobile, and the homepage looks good!

Yeah, sockets don’t really work right on free hosting. Looks like you got it working, so that’s good!

That just looks like an advertisement for Hostinger, which does not offer free domains (the price is just looped into the cost of the hosting). 

Once it’s finished a list of requirements will be shared, more premium hosting providers should be able to support it. 

I mean I don’t see them becoming much popular then they already are. Your bigger TLDs (com, net, org) will always be the most wanted ones, and will never be free. 
 

free domains seem to be for people with tiny budgets, as soon as someone has more money they want to put into their site, a domain is often one of the first things that is bought. 

Follow the instructions in the README and ask a more specific question if you have one.

If you want TXT records on the root domain, use the SPF feature.

I thought (but have not tested) that the ‘bug’ that prevent non-SPF records to be added as SPF records has been fixed. 

You need to upgrade to premium or use an external DNS provider (only if you have a custom domain)

Reset the password or contact support

If you registered your domain with Cloudflare, it is not possible to use it with MOFH since Cloudflare does not allow you to change your domain's namservers (The DNS 'NS' record, and nameservers are different things, they are not the same).

If you have had the domain for a bit, you can transfer it (I use and recommend NameSilo). Otherwise, you will need to register a new domain to use with MOFH.
