PHP Error Upon New Update

We are having a strange error after our hosting server updated the PHP version for our website. The plugin Tabs Responsive has been fully updated but no longer seems to be compatible with our version of php.

The error messages we are getting are:

Warning: count(): Parameter must be an array or an object that implements Countable in /home/customer/www/grizzlyseals.com/public_html/wp-content/plugins/tabs-responsive/template/content.php on line 24

and

Warning: Invalid argument supplied for foreach() in /home/customer/www/grizzlyseals.com/public_html/wp-content/plugins/tabs-responsive/template/content.php on line 146

My knowledge of php isn’t good enough to understand what is wrong or what the message is trying to get me to figure out. Has anyone else seen something similar to this in the past?
