I accidently deleted the subdomain that was created when i created my, any way to get it back?
It is very easy I suppose.
Go to subdomains module in your control panel and then on the subdomain suffix dropdown list just find the suffix of your original domain (for example if it was .rf.gd choose rf.gd) and just enter in the text box the same subdomain name that you had before.
If you still kept the folder of your subdomain and you re-create the subdomain it will probably get assigned to the same folder so you won’t have to change anything in file manager.
If you have any other questions, feel free to ask them here.
Have a nice day!
