Hey Chanidavis,
first of all, thank you for the purchase!
The “Appearance -> Customize” menu section is not intended as a settings source in Ikebana; even though it does work on my machine. You can set the website’s title and tagline in the “Settings -> General” admin section (though I recommend using the built-in “SEO Options” plugin for more elaborate SEO settings. You can set the front page in the “Settings -> Reading” admin section. In case you still need to definitely use the “Appearance -> Customize” menu section, please provide your admin login and password by emailing me at support@satoristudio.net, I will troubleshoot the situation.
Sincerely,
Andrii / Satori Studio
