Hello! You can turn off a debug mode there to hide the warnings. It will be fixed in the next update.

Hi ! how do you mean with the debug mode? the site will be officially online soon. when do you think there will be the next update? You can also give me the path to the file and tell me what I should change so that I can fix this error myself.

Best regards

Please check the article on how to turn off it: https://wordpress.org/support/article/debugging-in-wordpress/

Hi ! wow you’re a funny guy i know this article but it’s not my job. if i buy a license from you i expect your theme to work. If it doesn’t work then it would be nice if you tell me how I can fix this error myself.

there is another problem. the background image ( header ) which can be set for all pages, but it is only displayed in the shop. your demo content ( header image ) remains on all other pages. look at the screen https://ibb.co/LkRXbYH – the picture should be in the header on all pages. but it is not !

I send you greetings

It is not an error. It is a warning. When you turn off the debug mode it is disappeared.
