If I click back, the page reflects the changes I made, but why the error? What causes this as I've seen it before, only this time it won't stop, I've cleared cache, but everytime I save this page the page goes blank white with json output.

I checked the console but my theme has no errors.
I have no error in my console except a 404 for a missing css file
I'm getting this error in 5.7.5.13
Any idea what the fix that was applied in 5.8 was? and if it could be implemented in 5.7?

<?php $c = Page::getCurrentPage(); if (!$c->isEditMode()) {
$this->inc('elements/tracking-codes.php');
} ?>
It has meant that I've had to hard code rather than use the Dashboard -> Systems & settings -> SEO & Statistics -> Tracking Codes - Not ideal, but not the end of the world.
$("a[href*=#]:not([href=#])") needs to be changed to $("a[href*=\\#]:not([href=\\#])")
Seems to be breaking jquery which subsequently breaks the ajax required for editing.
Hope that is helpful for anyone else running into that issue on that particular theme.
