Hi folks!
On Tuesday, Aug 27, 2019, we deployed a change that will remove the predefined jQuery and Fancybox script options from the builder. This used to be checkboxes at the bottom left of “Manage Scripts” modal when adding custom JavaScript to your pages.
We removed this since jQuery isn’t as ubiquitous as it was when we added it, and the version that used to be in the app was an old version (v1.4.2)
One thing to note though, existing pages with the script enabled prior to the removal would not be affected and would be seeing a new script added to that page that loads the jQuery 1.4.2 CDN.
Moving forward, if your page require jQuery, you’ll have to add it to the page as JavaScript with the appropriate version from https://code.jquery.com.
