JQuery Error that is stopping other scripts

[fuadmurad]

Hi, I recently purchased a plugin for popup boxes and other types of lead generation functions and it was not working.  When I sent a message to their support team they sent me back this message Hello, We have checked your website and apparently you have a jQuery error that can stop all the scripts that are written after it and this may cause the lightbox not to show. If you open the console, you will see what I am talking about: http://screencast.com/t/RcpbUNy4WMV http://screencast.com/t/7zfskWmBPHt I can apply a fix if you provide FTP creeds but after the theme update, it will be overwritten. Therefore, please contact the theme developers to solve this issue. Thank you! Ovidiu   Is there anything that can done about this error because this same error popped up when I was checking my site speed and analyzing problems. Thanks

Thanks for the screenshots, yes the plugin author's observation is correct here. $ is missing in the file, you can fix it yourself also by adding $ inside the function() (http://prntscr.com/d5vtil), we will also fix this in our next update. You need to write it like this: function($)

Which file am I supposed to be editing exactly?

Ok, I checked the code but in wplms theme and wplms plugins I couldn't find this code. Please confirm from the plugin author from where they took this screenshot. If the code is present in the wplms customizer plugin or the blank child theme, then it is coming from your customization and it will not be updated.
