Hello sramselaar,
Thank you for contacting WooCommerce support
I understand you’re encountering an issue on your checkout page. Where you have selected a product option, but when you attempt to add the item to your cart, an error prompts you to choose an option, as if it were not recognized.
Since this could be related to a variety of causes, including conflicts with your theme or other plugins, or possibly a JavaScript issue, I need to take a closer look at your system’s configuration.
Could you please provide us with a copy of your site’s System Status Report?
To access this report, please follow these steps:
1. Go to the WooCommerce section within your WordPress dashboard.
2. Navigate to ‘Status’.
3. Click on ‘Get system report’ at the top of the page.
4. Then, click on ‘Copy for support’ to copy the entire system report.
Once you have obtained the system report, please paste the text onto https://gist.github.com to create a Gist. This will generate a link that you can share with us.
By sharing the Gist link in your following reply, we can review the detailed report and better understand what might be causing the problem.
We appreciate your cooperation and are looking forward to your response so we can help resolve this issue for you. ??
Best regards.
