Dear Mukhlisweb,

But error this message
Call to undefined function get_post_thumbnail_id() in /home/mindweb/public_html/wp-
content/themes/rttheme9/gallery-template.php on line 53
Help me please…
Thanks
I’m getting the following error: Fatal error: Call to undefined function get_post_thumbnail_id(). What am I to do? ?
This error says that your theme doesn’t support thumbnail option, in order to add this option please find ‘functions.php’ file in your theme and add the following strings to this file:
add_action( 'after_setup_theme', 'theme_setup' );
function theme_setup() {
add_theme_support( 'post-thumbnails' );
}
After that your theme will support thumbnail option and the error won’t display again.
I have problem this plugin in

We cannot open this page https://mind.web.id/?page_id=64 – it couldn’t be found. Maybe this website is running on your local environment? If so then please provide several screenshots.
