MyBB Community Forums

i just installed a copy of mybb .8 and it set url to
https://www.braindirector.com:443/forum
i do not understand what is that 443 and why is it there?
and will it create a problem (if it related to ssl) if in future i change the board url to http?

443 = default SSL port. You have to update the URL in settings each time you change domain, http(s), etc. But that's not a problem since it takes 1-2 minutes.

and it will not cause any problem with database if i change domain (https/http)?

Since 443 is the default port for SSL, you don't have to specify it in your board url setting.

I did not specify it. It was auto selected by mybb and then i removed 443 from the url
