Comment (by genevish-graphics):

 Hi All! Just found this thread after having the issue with the customizer
 not loading. My clients URLs are set differently. If I install the
 workaround plugin, will it do anything to the site? Just install it as a
 reg plugin and the customizer will load? Have never installed a workaround
 plugin and just want to be sure I can safely install this on my clients
 website. Thank you!
