Content background and footer missing after installing plugin

I installed a plugin that immediately removed my content and footer white background. I deactivated the plugin and uninstalled it but this did not fix the problem. I went through my files to see if any had been updated with the install of the problem plugin and I cannot find any files that were changed (by date). Also, I deactivated all plugins and activated them one at a time and still the content & footer background remain missing. I have no idea how to fix this. I have uninstalled and reinstalled the theme as well (Goodspace theme). Nothing is working, please help!
