Why I get a 404 (page not found) error?
That is a very common WordPress issue with Permalinks, not related to the theme (even if we're really trying to prevent it). To fix it, all you have to do is navigate to Settings - Permalinks and hit the "Save Changes" button. That's it!
How can I change a Custom Post Type name? (for example: "rooms" to "villas", "deals" to "offers", etc.)
Well, this is one of the most common and tricky questions about Hemma. First of all, we recommend to activate the child theme: this is a very important step because your changes will remain untouched during the theme updates, and you will not have to go through this lengthy process again.
Then create a functions.php inside the child theme's directory, you can add there some custom code to change Custom Post Type names. Take a look at this repository on GitHub, you can also find a sample file that shows you how to configure the functions.php file the right way!
