This has been fixed.
A simple flush of the database fixed it.
I figured out what the problem was. Because this was an old custom theme it did not have the <body <?php body_class(); ?>> code in header.php.
Adding this in fixed the problem.
Thanks for the reply.
No There is no custom skin. The skin is set to use the default one called ‘Main plugin folder – master’.
I have figured out that there must be a theme conflict because when I change the theme to twenty sixteen it picks up the default skin css without a problem.
I am currently using a custom theme that is quite outdated and old now. This is the live version of the site () which does not have the plugin. I am working from a offline copy.
What is the best way to fix this conflict?
