Hello @samkh63,
Thank you for reaching out — we’re happy to help!
Could you please confirm when did the issue start occurring? Was adding or saving variable products working correctly before? Has the issue started after making any specific changes to your site, such as installing a new plugin, updating a theme, or adding custom code?
In the meantime, you can perform a conflict test to rule out any theme or plugin conflicts that might be causing this issue. The best way to determine this is by?running a full conflict test.
To test, you’ll first want to change the theme on your site to Storefront, then check to see if the issue is still present. If that resolves the issue, you’ll want to get in touch with your theme’s developer and see if they have an update or fix for you.
If changing the theme doesn’t help, you’ll want to deactivate all plugins except for WooCommerce and take a look. If that fixes the problem, re-enable the other plugins one by one (gradually), checking after each, to see where the issue is coming from.
Be sure you have a good backup in place of your full site and database. You can ask your host for backup functionality or you can consider using a service like Jetpack. If something goes wrong, you will be able to restore it.
Let us know once you have done a conflict test!
