Maximum request length exceeded

I don't think the number rules is the issue here. I've seen this a couple of times where authentication cookie gets expired and not updated successfully when the reauthentication happens.

Can you try to either clear your cookies and cache or try an incognito window to see if that helps?

Thanks to both but nothing I'm trying is working. I restart the server, I'm using 3 different browsers and I also clean cache.

Now the problem is that I have a forever spin 😞 It doesn't allow me to open the form anymore.

I can still open views but not the form.

Any other idea? 

Hi, 

Maybe this will help:
