In order to change the Base URL, Luis refers to a Sites menu In a post on stack overflow a couple years back, where you can update the base URL to your domain, but I’m missing the Sites link underneath the System menu. In a separate, working version of ContentBox, I do see a link for Sites underneath System in the menu, but not in this case. Screen print of admin is attached. The “Sites” link should be under Geek Settings, but, probably due to the fact I only have one site, no option exists to switch it.
In addition, when comparing my working ContentBox version from the other install, I have a cb_site table, where it appears the “base url” may be tied to the domain column. I do not see the cb_site table in the version of ContentBox in question. I’ll do more digging.
