Hello i receive in console 404 error on files /meta-box-tooltip/js/tippy-bundle.umd.min.js.map AND /meta-box-tooltip/js/popper.min.js.map. Checking folder the files does not exist. It's normal or not?
The JS source map file is used to debug the error easier, it does not cause the error on your site. The popper and tippy js files are the library of Bootstrap so I think there is a plugin or block of code that conflicts with the code in those files.
