Hi,
we recently converted our project from 6.10.3 to 7.5.1. Now ever since the conversion when attempting to login we get an error in the console :
Uncaught (in promise) TypeError: Cannot read property 'insertBefore' of null

After some investigation I discovered that in mx 7 the function 'insertBefore' has been deprecated, however i do not know how to resolve this or even what widget is calling this out-dated javascript.
Has anyone experianced this issue, or knows how to fix it?
