Sometimes, shortcodes appear in the post excerpts on the archive page of WordPress site. This is a common issue with excerpts in WordPress due to theme or plugin issues. This can be very easily fixed.
Remember: These methods will work only if the shortcodes are registered with WordPress. If you are trying to remove shortcodes those got remained after deactivation and deleting the plugin then this will not work, because now those shortcodes are not shortcodes anymore, they are just a piece of text for WordPress. In this case, you need to manually do it, sadly.
Solution
Simply add the following code to your theme’s functions.php file. This code simply tells the wordpress to omit any shortcodes appearing in the post exerpts on archive section.
function strip_shortcode_from_excerpt( $content ) {
$content = strip_shortcodes( $content );
}
add_filter('the_excerpt', 'strip_shortcode_from_excerpt');
