Hi B ,
I hope you are well today and thank you for your questions.
How can i setup that the Blogpage is in full width. (only the Blog page)
In the Theme Settings i can Setup a Blog Title. How i can change it to the Pagename. I tryed to create a Shortcode that shows “the_title();” but it doesnt work in the blog title.
Could you please share me the blog page URL from your site so that i can help you to achieve it?
I want to modify the content.php from your theme. How do I make it, that I have this file only in the Childtheme? (that i can still update your theme)
Yes copy and add that file in the child theme of Jevelin theme so that you can modify it without affecting theme updates.
