Hi there,

I’ve experienced two issues on my php laravel website:

1. When deploying the website with vapor, I get the error message “HTTP header is larger than 10240 bytes.”. I have 10-19 cookies in use, even after removing them, logging out and stuff. Idk.

2. I always get the error message “Invalid state” from Auth0\SDK\Exception\StateException. Doesnt matter if in test environment or in deployed.

I think both of them are having issues with /logout, its something with the cookies/sessions not being deleted I guess?

How can I fix that?
