Hi, I am trying to activate the Virtual Phone Number Selling Form WordPress Plugin. Each time I try to activate the plugin I get this error:
Plugin could not be activated because it triggered a fatal error
Fatal error: Call to undefined function esc_htm__() in /home/univoxco/public_html/wp-content/plugins/vpnsf/voip-vpns.php on line 123
We have a clean install of WordPress 5.1.1 and running PHP version: 7.2.7
Can you please assist
