@ montymcmahon
I am interested in what you’ve developed
– can you send it to me please?
Fixed it, change the code to this…
add_theme_support( 'post-thumbnails' );
set_post_thumbnail_size( 825, 510, true );
It’s my own theme,
this is what i have in my functions file
add_theme_support( 'post-thumbnails' );
add_theme_support( 'post-thumbnails', array( 'post' ) ); // Posts only
add_theme_support( 'post-thumbnails', array( 'page' ) ); // Pages only
add_theme_support( 'post-thumbnails', array( 'post', 'movie' ) ); // Posts and Movies
