jQuery Forum

It is a wordpress site. I'm trying to help someone use the thrive plugin to build some landing pages, but apparently it has a conflict with the theme - diamond.  This is the error that is coming up and what I'm sure is causing the issue. I've tried calling jquery in the functions.php file.  I don't know.  I'm still learning dev for wordpress. I can't seem to locate the offending code.  It doesn't help that my time is limited with many distractions, so I'm sure I'm looking right at it, but my ADHD is just not letting me see.  

Would anybody be kind enough to help me?  Please let me know what you need, if I need to paste code, etc. Where I need to look, what I should try, any good debugger (besides using chrome to inspect and debug)?  

Thanks!
