customize page is blank after installing wordpress 4.7.2

Can you create a “test admin” user and see if you can access the customize page then? Also, silly question… but have you tried different browsers, clearing out cookies, etc..?

I would also disable all plugins – even the pre-installed plug-ins that come with a fresh WordPress install. If that doesn’t work, try to activate another “default” theme and see if it works.

error code: 523
