Strip HTML tags from the excerpt

Hello Roman,

I can see that you haven’t responded to a support question in 7 years.
But, you did update the plugin 1 year ago.

I’ve made a micro alteration to the code. So, if you do decide to update the plugin, please include the alteration.

From
$temp_excerpt = get_the_content();
to
$temp_excerpt = wp_strip_all_tags( get_the_content() );

Thank you
