Concat issue?

[TonyKnibb-MakaraHealth]

Error:
Cannot read properties of undefined (reading 'concat')

I'm using jquery 3.3.1 and I've tried 3.6.1 also

jquery mobile is 1.4.5

I am also getting the same error. I upgrade my jQuery version from 2.2.0 to 3.7.1.

Any solution?

@pardeepzapbuild It turned out that jquery mobile 1.4.5 won't work with anything newer than jquery 2.2.4

I ended up having to use jquery 2.2.4 on the one page that required jquery mobile 1.4.5, and jquery 3.3.1 everywhere else.
