Hello Murat,

Thank you for reporting this issue. I apologize for the inconvenience you're experiencing with the template installation.

To help me investigate the "Database Not Set" error, could you please grant me temporary administrative access to your site? This will allow me to examine the configuration directly.

Before you provide the credentials, please ensure you have a complete backup of your site for data security.

Looking forward to your response.

Best regards

my site currently localhost xammp server. i got this error only shaper components and templates. i think is not compatible with joomla 6

Apolozy for the inconvenience. Please note that our latest version of the Helix Ultimate template is fully Joomla 6 compatible. If you are experiencing issues on your localhost, it may be related to an older version or a local server configuration. We recommend updating to the latest versions to ensure full compatibility.
