Thanks! That fixed it.
Just thought I should mention that the Custom CSS box in my child theme gave me an error when trying to save the changes.
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘weblizar_sanitize_text’ not found or invalid function name in /home/username/public_html/wp-includes/plugin.php on line 235
So I just added it manually to style.css and that worked fine.
Thanks for your help!
