Can't access the control panel

[FlamurR]

A guide from you might help me more cuz the one that are here already... I don't get a single word on what they mean. :S But yeah i think i installed SSL correctly this time it shows https:// and the lock, my only problem is that i can't make a subdomain to work idk why what do i need to configure on the DNS and do i need to do anything at all the place where i got the domain, i got it from godaddy do i need to setup something there aswell?? Btw im not able to get to the website without typing https://.

EDIT: Whenever i try to enter the website with https:// it takes me to the control panel but without https:// it takes me to the actual site. OMG whats going im really confused pls don't go hard on me im really a noobie but im a fast learner so some lil explanation will really help me Thank you...
