Sounds like a hosting problem or local MAMP/XAMP setup error.
Can you reinstall WP & Customizr again?
im using a multisite. main site is a business directory and business page site customizr theme. when i finished uploading and organizing all pages on my business page, theme and plugins got crazy. now even my main site business directory is messed up, deleted all my media. contacted my hosting, still got no answer. thanks rdell.
This sounds like problem with your site, not this theme specifically. Have you tried deactivating your plugins and switching to a default theme?
If the problem persists, you should ask on the multisite forum.
