Site crashed

This site would not load today and presented the following error:

Parse error: syntax error, unexpected ‘)’ in /nfsvol-www/80/68480/kelownafirearmstraining.ca/rbl_wordpress/wp-content/plugins/testimonial-basics/includes/katb-functions.php on line 1016

I was able to login into the cpanel, and using the file manager renamed the plugin to disable it. The site now loads.

Any suggested fix?
