Yeah right. I didnt realise they had an client area. Yes, the domain limits are enforced. This is the absolute maximum: (hey look - we can finally upload images) (I guess its about 3000 technically - parked domains dont count)   Either way, noone is actually gonna try to host that many sites, and there is no practical use. Even if you maxed that out, each sites gets a few views a day and your account is over the hit limit...  

To have a website you need at least an index file, so each domain is 3 inodes (domain folder, root folder, index file) / 50,000 inode limit x 3 accounts. accounts and inodes divide out, so 50,000. Did not count the domain limits as I can't recall if there is actually an enforced one on addon domains. (1200 max if you are only using subdomains as that limit would be reached before the 50,000)

Youd actually hit the domain/sub/addon domain limit first. Limit should be somewhere arround 4k. Also, it creates two folders for each domain, so more like 25k, if that was the limit.

Known issue, supposedly being worked on

Hey, I’m setting up my MOFH reseller with my custom domain hostilio.cloud. I pointed the nameservers to ns1.byet.org through ns5.byet.org, and DNS seems to be working fine. But when I try to add a subdomain like cpanel.hostilio.cloud for the control panel, I keep getting this error: “Invalid Domain, please check your input.. 99” Anyone know what’s causing this or how to fix it? Thanks.
