webpackJsonp is not defined when updating Ionic
(Last Updated On: February 12, 2018) This is a really stupid error that can happens when you update your ionic dependencies (Never touch a running system!!! but well sometimes we have to).
It happens because the way Ionics build the scripts have change along the way and your project does not find all the generated javascript, Probably the file missing is vendor.js so as for Ionic 3.6.1 just be sure that your src/index.htmlhas this base structure.
