Hello,

Actually, I am a support agent and Xtemos (Author of the theme) uses my personal email to create my account on the support system that is why you get the response from my Gmail ID.

You can change the logo from Woodmart >> Header Builder.

You can change the footer login by editing Widgets from Appearance >> Widgets.

In case you need help then provide the login details of the website.

Best Regards
