theres no header editing when I use customize of the whole site ,how to edit hea

Hello, @liudavid,

Thanks for sharing the screenshots to understand your issue better.

The demo you are using has the header and footer created from the template builder.

Please navigate to the Dashboard >> Porto >> Template Builder >> Header >> From there simply edit the header https://postimg.cc/34d1wjxC and Dashboard >> Porto >> Template Builder >> Footer >> https://postimg.cc/sMjpXPnQ edit the footer block as per your needs and then save settings, changes will appear on the site automatically.

Further, I have attached some articles below please check to understand better how to use header builder and footer builder in Porto Template Builder:
