It’s not working

I guess your WordPress theme or other plugins removed the wp_head part that courses the Coronavirus Data plugin can not output the definitions.

This plugin runs smoothly on themes meet the WordPress standards.

If you can not solve problems, try to open a support post instead of rating this plugin to worst, it’s irresponsible.

I had solve this problems.
A bug in wp-content/plugins/corona-virus-data/includes/class-corona-virus-data.php
You need vi class-corona-virus-data.php and find “cov__history_global” and “cov__history_c” add “;”.
before
var cov__history_global = “‘ . __(‘Global Daily Data’, ‘corona-virus-data’) . ‘”
var cov__history_c = “‘ . __(‘Daily Data’, ‘corona-virus-data’) . ‘”
var cov__popu = “‘ . __(‘Population’, ‘corona-virus-data’) . ‘”
after
var cov__history_global = “‘ . __(‘Global Daily Data’, ‘corona-virus-data’) . ‘”;
var cov__history_c = “‘ . __(‘Daily Data’, ‘corona-virus-data’) . ‘”;
var cov__popu = “‘ . __(‘Population’, ‘corona-virus-data’) . ‘”;
