/**
 * Register all custom fields after the plugin is safely loaded.
 */
function wpas_user_custom_fields() {
/* You can start adding your custom fields safely after this line */




/* Do NOT write anything after this line */
}

When using wpas_add_custom_field() or wpas_add_custom_taxonomy(), please make sure to wrap them inside a function_exists() check.

Example

if ( function_exists( 'wpas_add_custom_field' ) ) {
    wpas_add_custom_field( 'my_custom_field',  array( 'title' => __( 'My Custom Field', 'awesome-support' ) ) );
}

I added it according to the instructions in the documentation, but still it's not showing up.
do I need to add any codes to the templates ?
