While creating the configuration products in Magento2.2.2 I am facing the
Invalid Form Key. Please refresh the page
error. I have google regarding this error and I have found the solution to
Increase the value of max_input_vars PHP configurable variable
I have increased this value but the problem is not solved.
While creating the configurable product almost 40000 associated product is generated and now I have set the max_input_vars
value to 3075000
but the problem is not solved.
Anyone, please help me to fix this issue.
