If you had already acquired some features before the packages launch (removal of ads, SSL certificate activation,...), the forum will take them into account when calculating the price of the package which includes these features. Indeed, a refund equivalent to the amount paid, less the time already elapsed, will be deducted from the purchase price of the package (if you choose an annual payment) or added to the forum credits amount (if you choose a monthly payment).

Hello,

Since the implementation of the packages, a custom domain such as a CNAME are reserved for forums that have acquired an Advanced or Premium package. Until today we tolerated some exceptions having kept domains out of packages. However, we can no longer maintain two-speed forums which requires adapting all our developments to the various existing exceptions... 

Therefore, if a forum is in a free package, a redirection is made to its base URL. In other words, in a free package, even if the forum has somehow kept a custom domain name or a CNAME, it will still be the basic forum url that will respond.

If the admin wants to use the forum with a custom domain or a CNAME as main address, it must be in an Advanced or Premium active package. 

Thank you for your understanding
