Your problem
My problem is : Since updating to 4.3.1 I am no longer able to create a new email nor edit existing emails in Channels → Emails. This appears to be the only issue. Nothing happens when you click ‘Edit’ or “+ New” except the top loading bar briefly shows activity and then stops.

Steps I have tried to fix the problem : I’ve cleared the cache both manually as well as the CLI. I’ve also restarted everything and thought it may have been a cookie error, but no such luck.

Update:

It works now that I’m not tethered to an AT&T iPhone. If I switch back to the tether it fails, but works if I’m on my home wifi.

I quit.

You quit AT&T?

Just a hunch, but some mobile networks will inject their own custom javascript into webpages over HTTP, usually to try and reduce the page size or rewrite image URLs to use more compressed version. Your network might be doing this, and it could be breaking some of Mautic’s functionality.

Have you tried accessing your Mautic installation over HTTPS? (this will take a little setup, but shouldn’t be too onerous)

Also, please check you have cleared your Mautic cache, used bin/console m:a:g just in case your production assets haven’t been updated, and also clear your browser cache.

If none of these help I would also be inclined to suspect something like @jlbs suggests above - certainly I had something like that with Vodafone here in the UK a while ago and had to turn off a bunch of settings on my account to stop it misbehaving!
