Problem¶

The AdminPanel javascript file uses a method Array.from which is not supported by IE11. The AdminPanel doesn't open any module and is therefore not usable at all.

Another occurencies of Array.from¶

• EXT:adminpanel/Resources/Public/JavaScript/Modules/Cache.js

Possible solution¶

Polyfill the method

• by using core-js
• or maybe with the help of https://developer.mozilla.org/de/docs/Web/JavaScript/Reference/Global_Objects/Array/from#Polyfill
