Hi Christian,
Thanks for reaching out.
I have checked your website and found the issue after creating a new sub-page. It only happens when the .htaccess file is not able to be modified due to the Permalink settings. If that is already working fine, there might be some different reasons behind your reason. I would like to suggest troubleshooting the following common issue to help us to recognize the reason.
- Theme Related Issue
- Plugin Conflict
- Theme Update related issue
- Child Theme Related issue
- CSS/JS Customization
- Disabling Cache
- Disabling CDN
If you discover that an issue is coming from a custom code or 3rd party plugin, kindly consult with a developer or contact the plugin author. Please note that we do not provide support for custom codes and 3rd party plugins.
If none of the above helps, please copy your live site to a staging server so we could troubleshoot freely without breaking your live site.
And give us access to the secure note including:
– WordPress Site URL & Login URL
– WordPress Admin username/password
– FTP/CPanel credentials as we may need to access the .htaccess file during the testing.
To create a secure note, click the key icon underneath any of your posts.
Thanks
