Hi,
Firstly make a child theme of the theme you have. Open functions file in the child theme directory go to last in this file and see the code below –
function enigma_activation_notice(){
wp_enqueue_style('admin', get_template_directory_uri() .'/core/admin/admin-themes.css');
?>
<div class="notice notice-success is-dismissible">
<p class="notice-text">
<?php $theme_info = wp_get_theme();
printf( esc_html__('Thank you for installing %1$s ? Version %2$s ,', 'enigma'), esc_html( $theme_info->Name ), esc_html( $theme_info->Version ) );
echo esc_html__( 'For More info about Premium Products & offers, Do visit our welcome page.', 'enigma' ); ?>
</p>
<p class="notic-gif"><a class="pro" target="_self" href="<?php echo admin_url('/themes.php?page=enigma') ?>"><img src="<?php echo get_template_directory_uri(); ?>/images/wlcm.gif"></a></p>
</div>
<?php } ?>
Replace this code with the below code and save the file after done. Activate the child theme and check the banner.
//function enigma_activation_notice(){
//wp_enqueue_style('admin', get_template_directory_uri() .'/core/admin/admin-themes.css');
?>
<!--<div class="notice notice-success is-dismissible">
<p class="notice-text">
<?php //$theme_info = wp_get_theme();
// printf( esc_html__('Thank you for installing %1$s ? Version %2$s ,', 'enigma'), esc_html( $theme_info->Name ), esc_html( $theme_info->Version ) );
// echo esc_html__( 'For More info about Premium Products & offers, Do visit our welcome page.', 'enigma' ); ?>
</p>
<p class="notic-gif"><a class="pro" target="_self" href="<?php// echo admin_url('/themes.php?page=enigma') ?>"><img src="<?php// echo get_template_directory_uri(); ?>/images/wlcm.gif"></a></p>
</div> -->
<?php// } ?>
Let us know if any query.
Thanks.
