This problem is occurred after adding more custom options and categories in the product so because php.ini file not allowed to add more custom options.

So, we need to change default settings of php.ini file.

If php version 7.1 then,

/etc/php/7.1/apache2/php.ini

If php version 7.0 then,

/etc/php/7.0/apache2/php.ini

If php version 7.2 then,

/etc/php/7.0/apache2/php.ini

Uncomment this value and update this all value in php.ini,

max_input_vars = 200000
max_input_time = 600
max_execution_time = 3600

Then Restart Apache 2 web server, and check it.

sudo service apache2 restart

There is one more source for this error: a wrong cookie_domain in the configuration. As you can't login into the admin area, you can check it directly via mysql:

SELECT * FROM core_config_data WHERE path LIKE '%cookie_domain%';

You can change the value in mysql directly as well. Don't forget to clear the cache afterwards.

This bug arises due to php.ini variable "max_input_vars" Increase it to 10000 through below php function:

ini_set('max_input_vars', 10000);

OR Using linux command line

cd /etc/php/7.0/apache2/
vi php.ini (Open for edit and set max_input_vars=10000)
:wq(Press esc and write the mentioned command to save and exit)
sudo /etc/init.d/apache2 restart(Restart Server)
