pop-up warning, i have reinstall woocommerce / disable all plugins expect woocomerce / tried with different themes but still i get this warning every time i try to edit/add product. What could be the reason for this warning / error
The “adding new attribute failed” warning in woocommerce could indicate an issue with the product attribute system. Check if you have any custom codes or plugins that modify product attributes. Also, verify if there are any conflicts between plugins or if your WordPress database is corrupted. Consider restoring a backup or contacting WooCommerce support for further assistance in troubleshooting this error.
The following worked for me:
Get in your WP dashboard, go to woocommerce, settings, advanced, then select the
characteristics (the last sub tab) it probably says something else in English, I have another language.
Then disable WooCommerce analytics. Solved this issue for me.
