I wanted to upgrade my platform to the more recent 3.2.1 jquery loaded from CDN :https://code.jquery.com/jquery-3.2.1
However when I do that I get errors like this
jquery.pjax.js:981 Uncaught TypeError: Cannot read property 'push' of undefined
at jquery.pjax.js:981
at jquery.pjax.js:991
caught TypeError: jQuery(...).pjax is not a function
at j (jquery-3.2.1.min.js:2)
at k (jquery-3.2.1.min.js:2)
Any ideas ?
Can I upgrade or should I stay with 2.2.4 where everything is working
