Something was preventing my pages from normal function, like viewing screen options, setting privacy settings, etc. After working an hour with the hosting tech, the only thing left to do was to turn off all the plugins and check each one. When I turned off all the plugins, the pages started working correctly. In checking my plugins, your Facebook Like Box turned out to be the culprit that broke the site. I noticed you updated it 10 hours ago. Maybe something went wrong. Please fix it.
Sorry, this caused you trouble :( I fixed this and updated the plugin, this caused due to - new like box preview option.
Please do rate our plugin in wordpress.org :) https://wordpress.org/support/plugin/cardoza-facebook-like-box/reviews/ :)
