404 on category links with “remove parent slug” on

Hello,

We apologize for the issue you are facing with the 404 errors on your category links when enabling the "remove parent slug" option. This can sometimes happen due to conflicts with theme settings or custom blocks in your mega menu.

Here are a few suggestions to troubleshoot this issue:

1. Check Permalink Settings: Ensure that your permalink settings are correctly configured in WordPress. Go to Settings → Permalinks and re-save your settings to refresh the permalink structure.

2. Clear Cache: If you are using any caching plugins, clear the cache to ensure that the changes take effect.

3. Theme Compatibility: Since you are using the Flatsome theme, check if there are any specific settings related to WooCommerce or permalinks in the theme options that might be causing this conflict.

4. Custom Block Configuration: Review the configuration of your custom block in the mega menu. Ensure that the links are correctly pointing to the updated URLs without the parent slug.

5. Disable Other Plugins: Temporarily disable other plugins to see if there is a conflict causing the 404 errors.

If these suggestions do not resolve the issue, please reply to this ticket, and a human agent from the Rank Math Support team will assist you further.

Thank you for raising this concern!
