Magento2.2.4 - Invalid form key while save product

Question

I have Magento 2.2.4.

I have tried increasing max_input_vars in php.ini file.

I have cleared var/cache, browser cache, removed domain cookies.

Still, get the error when trying to edit an existing product. But, I can create new products without any issue.

Error: Invalid Form Key. Please refresh the page.

Working or not?

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

So, required to change default settings of php.ini file.

Now, Edit your 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

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

max_input_vars = 200000
max_input_time = 600
max_execution_time = 3600

Now Restart Apache 2 web server, and check it.

sudo service apache2 restart
