[PAYH] Is SSL a no-cost option for trail users?

[#1]

Dear PlusNet PAYH trial support folks,
Whilst checking the options available in the (new to me) Plesk Control Panel I note we can enable SSL (and indeed it works) - I assume this is a "no cost" option?
...later: see follow-up post for the SSL "gotcha", it works, but ...
Many thanks for your support.

Have found the "gotcha" - the SSL certificate is, shall we say, "not ideal"  (see attachment)
So, am guessing that there won't be a charge for this SSL - but many (most?) might find the SSL Cert off-putting and thus it isn't a great option as it stands, never mind was a nice idea initially.
