From magento ce 2.3.4 admin just in configuration module I can not save or saving button is not working:
a) Firefox most of the time not working
B) google chrome sometimes not working
c) Microsoft edge works ok
"TypeError: d is undefined" related to https://cdn.mysite/pub/static/versionxxxxxx/adminhtml/Magento/backend/en_US/Dotdigitalgroup_Email/js...
In order to resolve the issue I have tried:
- fix permissions of folder and files, no luck
- clear and flush cache, sometimes works
- deploy the site, sometimes works
anyone has a solution or experiences the same issue?
at the same time, I am using, nginx, varnish apache and pagespeed.
