Hello Joe, thanks for purchasing Cesis!

First for the slider part, you need to go edit the "Content block" ( Content Block, then search for Banner - Agency Home ).

For more information, please check the documentation :

For the front page, if you want to edit the theme Logo, menu style etc you can do it from the "Cesis" tab of the wordpress dashboard but the page you imported is using custom settings.

Please go edit the page and scroll down until you see the "Page options" theme panel, then check each tabs and turn the "Custom settings" to off.

Then update the page, this should do the trick!

Do not hesitate to contact us if you have more questions.

Have a nice day!

Regards.
