magento 2.3.4 configuration admin not saving

[Isidoro_]

Good day,

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

console says:

"TypeError: d[0] 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.

Hello @Isidoro_ 

Can you please disable Dotdigitalgroup_Email module?

Before disabling the module, do read the following:

I hope it helps.
