Hello!
Thanks for getting in touch with us. My name is Muhammad and I will be your support rep.
Can you please share the WordPress admin user details so I can check your customize area issue?
You can edit the logo by navigating to wp-admin>>appearances>>widgets and editing the pre-footer area, for more info please check: https://xstore.helpscoutdocs.com/article/48-widgets-custom-widget-areas
Please let me know if you see any issue or need any help with the logo query, I would love to help you.
Thank you!
