Tweak: Remove non-SSL fallbacks for Security Check Pro and Version Management.
Bug Fix: Tweak checkbox styles.
Security Improvement: To improve server compatibility, requests to the iThemes updater servers would automatically downgrade from https to http when https connections failed.

define( 'ITHEMES_ALLOW_HTTP_FALLBACK', true );
