Variant number limited?

Some people have said they have hundreds of variations, though that sounds rather difficult to manage to me.

Have a look at your php’s max_input_vars setting. You’ll find it in WooCommerce > System Status. 1000 is the default, but increasing this value may help.

The next step would be to deactivate all other plugins and test. Does this fix the problem?

I thought about until it is on the memory limit and put it on 256MB and PHP Max Input Va to 5000 – it still was not working .

I installed another theme and activated all 50 variants and its works withe the theme.
What can the errors of my theme be ?

Did you deactivate other plugins but still using your theme? The idea is to isolate exactly which software element is causing the problem.

If you have only your theme and WC activated, and still have the problem, you should go to your theme’s support service. The theme author knows his theme best and www.ads-software.com forum members don’t have access to commercial themes.
