[Variable] Default Variation Doesn't Work

This behaviour is typical of an insufficient value for PHP’s max_input_vars setting. You can find your current setting at Admin page > WooCommerce > System Status. You can increase it with an extra config line in php.ini or .htaccess. Your host’s techs may be able to do this for you if you have difficulty.

Hello lorro,

Thank you for replied my questions.

So, these are the config on my website :
WP Memory Limit: 40 MB
WP Max Upload Size: 2 MB
PHP Post Max Size: 32 MB
PHP Time Limit: 600
PHP Max Input Vars: 1000

So, I need to increate “PHP Max Input Vars” value? Is this only editable through .htaccess?

This plugin worked for me and help me manage my variations with no pain.

“PHP Max Input Vars: 1000” is not a very large number if you have a large number of variations. Try this in php.ini:

max_input_vars = 5000

or this in .htaccess:

php_value max_input_vars 5000

If your PHP is using suhosin then extra lines are needed, or if you don’t know where php.ini is, or if your host does not allow its customers to edit php.ini, ask your host’s techs do do this for you.

Thank you! I will try that one.
