@bdolor all new BS4 scripts are loading in the right order as per BS4 docs, but errors persist.

The Uncaught ReferenceError: Popper/Tooltip is not defined errors are coming from the following BS4 js files:

• /bootstrap/js/dist/tooltip.js
• /bootstrap/js/dist/popover.js

I've tried the following actions to no avail:

• Using bootstrap.bundle.js (combines popper.js with bootstrap.js)
• Separating bootstrap.js and bringing in popper.js separately (in the correct loading order)

The Uncaught TypeError: Cannot read property 'fn' of undefined error is coming from popover.js
So if you're also satisfied BS4 .js files are loaded correctly, and in the correct order... then I'd to pursue this and switch the jQuery version, as BS4 requires jQuery 3.x and WordPress core is at 1.11.4

Tested updating core to jQuery 3.3.2, caused a lot of errors... mostly due to WP core jQuery scripts (and our own) using the formerly acceptable jQuery(document).ready(function()..... which was deprecated as of jQuery 1.8 and removed in jQuery 3.0 More info here
