Answer 1

Also you can see this error message when your form has a lot of elements.

This option in php.ini cause of problem

; How many GET/POST/COOKIE input variables may be accepted
 max_input_vars = 1000

Problem is that _token field misses PUT (GET) request, so you have to increase value.

Also, it concerns a big files. Increasing the

upload_max_filesize

option will solve problem.
