Hi, if the update you are referring to is SP Page Builder 3.8.3 (released today) then, unfortunately, it doesn't solve the problem. Still seeing the same errors.
Note: I noticed just now that the URL I provided initially was to our production site (sapfm.org) which has not been modified to use this 404 error handling approach. I have updated the hidden data to point you to our development site (where the error can be found).
Unless I made some mistake, and I have reviewed/checked it multiple times, following the instructions provided in your article (cited in the original note of this thread) will generate two errors:
Uncaught TypeError: "...tooltip is not a function" (coming from "/components/com_sppagebuilder/assets/js/jquery.parallax.js")
and
Uncaught TypeError:"... Cannot read properties of null (reading 'data')" but, I suspect, is just a knock-on error from the original jquery problem.
