Error: "There was an issue while creating the group. Please try again."

When you save an option group in WooCommerce Product Options, you might see an error: "There was an issue while creating the group. Please try again.". The sections below summarize the most frequent reasons for this error.

Outdated MySQL version

One possible cause of this error is that your website is using an old version of the MySQL database, which we no longer support. Please ask your web host to update MySQL to a newer version, which should resolve the problem. You can find our plugins' minimum server requirements here.

Disabled intl PHP extension

The error may also be accompanied by a notice stating that the server encountered a critical error because the Transliterator class was not found. This error means that your server does not have the intl PHP extension enabled. To fix this issue, you should get in touch with your hosting provider and ask them to enable the intl PHP extension.

Please bear in mind that WordPress added the intl PHP extension to the list of recommended modules that every provider hosting WordPress installations should have enabled. The check for the intl extension was added to WordPress 5.9. If you use the Site Health tool to check which mandatory or recommended modules your server is missing, the intl module will certainly be listed there.

X-Http-Method-Override header not accepted

Finally, it would help if you also verified that your server allows the GET, POST, PUT, and DELETE HTTP methods through the X-Http-Method-Override header, which is how the core WordPress scripts send REST API requests. Those methods are used by WooCommerce Product Options to list, create, edit, and delete option groups. Therefore, the plugin will not work properly if your server doesn't allow any of those methods and doesn't accept the X-Http-Method-Override header. Please consult your hosting provider to verify that your website configuration meets that requirement.
