WordPress @include( ‘template-config.php’ );

Something in your theme is not written properly. I can’t tell you what it is exactly as I don’t know what your code is.

Seeing as that code is supposed to be php, and is being shown on your page, I am going to assume that there is no <?php ?> tags around it, and it is being shown as if it is text as the theme does not know it’s supposed to be php.

Check your error log on your server to get an idea of where the issue is.

What you should do to get access to your site again is in CPanel, rename your active theme’s folder to something else (wp-content/themes/yourtheme/). This will manually deactivate the theme. If the issue is the theme itself, you will be able to access the backend of your site.
