 * My website’s header suddenly disappeared and I am unable to customize the theme
   anymore. The error all my readers are getting is the following:
 * Warning: Illegal string offset ‘custom_css_post_id’ in /home/content/n3pnexwpnas02_data02/
   15/3809715/html/wp-includes/theme.php on line 905
 * Please help, I am clueless about this issue.

 * Hello,
 * Do you edit any main theme’s files or install any plugin. It may be a plugin 
   conflict. Try to deactivate all the plugins and activate one after another until
   you find the faulty one.
 * Can you please post a link to your site where I can see these issue so I can 
   assist you better.
 * Thanks
