**Your software**  
My Mautic version is: just updated  
My PHP version is: 7.2

**Your problem**  
My problem is: 431 errors and unavailable screens

These errors are showing in the log:

Steps I have tried to fix the problem:  
Much testing.  
First guess was long header, but looking in the debugger said otherwise.  
Unfortunately, shortening my quite long naming conventions fixed it for most but not all pages.  
After a day or two it was back.  
Switching browser fixed it.  
Then it was back  
I cleared wordpress cache and disabled wp\_security in case they were impacting because mautic is in a sub directory of wordpress. no help

Hired an expert, that lead to an update which brought its own unique problems then back to the same old grind.  
After a day away form it, I realised it had to be cookie sizes.  
I checked and sure enough there are a lot of huge cookies set by mautic.  
I researched and sure enough many browsers lead by chrome have dramatically reduced the max storage of cookies in recent versions.  
I deleted all cookies for mautic on all browsers and everything worked just fine.

Why is everyone not screaming about this?  
I was testing continuously:  
43 emails and 88 landing pages; that’s a lot of clicking and testing and cookies.

Of course I could be wrong about all of it. Maybe I am having a golden patch this week.  
You decide.  
If Im right, then your solution will soon be only usable for amateurs with little websites
