I was logged in to my laravel 5 application. Deleted all my cookies, and suddenly get the TokenMismatchException error when i try to re-login.
It only happens in the browser (google chrome) where i deleted the cookies.
Does anyone know how i could fix this? And why i have the error in only 1 browser?
When you're using a CSRF token in Laravel, here's what happens:
client makes a request for the form (or whatever page)
form includes a special CSRF token which is also saved on the server and associated with that client's session
form is submitted, and CSRF token is passed back to the server
server checks the CSRF token against what it has saved for that token - if they don't match, you get an error.
If you loaded the form and then cleared the cookies, you've deleted the session key that associates that form (what's displayed on your client's screen) with the session on the server. The server has no way of knowing that that form submission should be associated with that session and that CSRF token.
There's a simple solution: after clearing your cookies, refresh the page in your browser.
