I was trying to change the image of the main page, so I went to appearance and then to customize, but it does not give me the possibility to edit the main page. This is what comes out:
I hope you are well today and thank you for your question.
Can you verify that you have the illdy companion plugin installed?
Appearance > about Illdy > Plugins.
If you do, try disabling any other third party plugin you may have installed and test the customization options once more.
I uninstalled the illdy companion plugin and it is the same. I can not edit customize
You did not have to uninstall the plugin, we just needed to ensure it was installed but you should have deactivated the plugins that did not come with the theme to see if one of them was causing a conflict.
