Hello,
First of all, please accept our sincere apologies for the inconvenience and the time you spent trying to resolve this.
Changing the homepage is not mentioned in the template documentation because it is not a template-specific feature. It is a core feature of Joomla. In Joomla, the homepage is controlled through the Menu Manager by assigning a menu item as the Default Home. The template simply displays whatever page Joomla sets as the default.
The issue you are experiencing is most likely caused by the multilingual configuration that is enabled in the Quickstart package. When multilingual functionality is active, Joomla loads the homepage based on the language-specific default menu item. In this case, a regular default menu item may not take effect if language-specific homepages are configured.
If you do not plan to use a multilingual site, you can resolve this by disabling the following plugins:
- System – Language Filter
- System – Language Code
After disabling these plugins, the normal default menu item should work as expected.
If you do need a multilingual website, please follow this guide which explains the correct setup process:
