How to troubleshoot before opening a support topic

In order to troubleshoot plugin errors, please try each of these steps and take note of the result after each step. Make sure to backup your database before doing this:

1 – Save plugin settings (WooCommerce /?Settings /?Products /?Product Customer List).
2 – Press on “reset column order” button (if you can see it in the product page).
3 – Delete and reinstall my plugin.
4 – Disable all plugins except for WooCommerce and my plugin. If this fixed the issue, please note which plugin causes the conflict.
4 – Switch your theme to Twenty Seventeen.

Thank-you
