JavaScript exception: Error calling selector function. Issue with breakpoints

[andrilla]

Getting this error: JavaScript exception: Error calling selector function: TypeError: $( '.breakpoint' ).registerBreakpoint is not a function. (In '$( '.breakpoint' ).registerBreakpoint()', '$( '.breakpoint' ).registerBreakpoint' is undefined)

Breakpoints are not working for a specific site. Works fine for all others. When scaling browser to a breakpoint under the main, everything goes white until the page is reloaded.

Did you figure out the fix action for this?  I have the same problem now.

I found a fix action for it.  I deleted all scripts in the HTML header of the master page and re-uploaded the site after that (re-upload changed pages only, which in this case was all pages since the master page applied to all pages).  No more errors.  I only had scripts in the HTML header of the master page, nowhere else.  I had the following scripts there:  Google analytics, cookiebot consent form, and robot text.  Today I will start putting the scripts back again, one by one.  Not sure which one thing caused the problem though.  Maybe just the fact of re-uploading the whole site fixed the action, or maybe there was indeed a problem with the HTML header scripts.  PS:  I am not a profesional web developer.  I also must admit that I had just changed the google analytics script from one account to another account, by selecting, deleteing, and pasting the new script into the HTML header of the master page....maybe I did not delete the entire old script correctly....

Suggest you spend a weekend learning proper HTML syntax.  It's essential if you intend to work with code.

Read chapters, do code exercises and take quizzes at the end.
