 * Hey there,
   I’ve just installed this plugin to try it out, but I’m getting the
   following error if I try and use the visual builder, or if I activate a tour 
   on a page.The full error is:**Warning**: Undefined variable $ in …/**httpd/htdocs/
   wp-content/plugins/dp-intro-tours/public/class-dp-intro-tours-public.php** on
   line **79**I think you’ve double typed the $ – Screenshot here:[https://go.screenpal.com/watch/cZfjlQVsOtO](https://go.screenpal.com/watch/cZfjlQVsOtO)
 * Subsequently, the tour also doesn’t launch/work.
   I’m on WordPress 6.4, with PHP
   version 8.0, Apache
