If one were to change the themes of a running site, or something major like that, I imagine they take their site 'offline', or shield the site with 'under construction' static page, while making sure everything worked.
How do I do this?
(I should mention i'm ok-enough at just swapping the site from hostgator to wampserver and back, but it's a pita and it plugins/themes become problematic. If there's a way to just leave it all on hostgator but block site-members from seeing it while under construction, that'd probably be easiest for me!)
Thanks for any input or tips on the matter!
