max_input_vars in php.ini Not Updating After Change

I changed it to many numbers starting from 2000 up to 5000. But every time I changed it it would not update the max_input_vars and would keep giving me the same error.

I found a solution, the max_input_vars value is stopped by default, only delete; symbols will start.

It should be enough with editing your php.ini file. It should look like this without ( ; ) second line :

; How many GET/POST/COOKIE input variables may be accepted
max_input_vars = 10000
