 * Hello, I’ve gone into metaslider to update my images however I can’t change or
   create a new slideshow as I keep getting this error:
 * HierarchyRequestError: Failed to execute ‘insertBefore’ on ‘Node’: The new child
   element…(jquery.js)
 * I also can’t get the full message of the error. If I attempt to create a new 
   slider I get this error:
 * Cannot read property ‘open’ of undefined
 * Please help!
 * Thanks
 * PS. all my plugins are up to date and I am running a child theme.

 * Hi,
 * You can typically find more info on the error by checking the browser console.
 * [https://support.airtable.com/hc/en-us/articles/232313848-How-to-open-the-developer-console](https://support.airtable.com/hc/en-us/articles/232313848-How-to-open-the-developer-console)
 * You might need to reload the page _after_ opening the console to see a full URL
   to the script that’s failing. Can you share that information?
 * 99% likely another plugin conflict though, so if you want to save some steps 
   can you disable all other plugins and try to narrow down which one it is?
