Problem with header after switching from X theme to Pro

[Luketina]

Hello, i have probelm with header after switching from X theme to Pro theme.
Everything else working fine. Now is my header duplicated.
I try to add new header by importing header template but i got error “Uh oh Failed to insert template”

And I get this error in wp admin background " header information - headers already sent by (output started at /home/customer/www/luketina.com/public_html/wp-content/themes/pro-child/functions.php:85) in /home/customer/www/luketina.com/public_html/wp-admin/includes/misc.php on line 1431"

Hi Zvonimir,

Thanks for reaching out.
There might be some different reasons behind your reason, I would like to suggest troubleshooting the following common issue to help us to recognize the reason.

1.Theme Related Issue
2.Plugin Conflict
3.Theme Update related issue
4.Child Theme Related issue
5.CSS/JS Customization
6.Disabling Cache
7.Disabling CDN

If you discover that an issue is coming from a custom code or 3rd party plugin, kindly consult with a developer or contact the plugin author. Please note that we do not provide support for custom codes and 3rd party plugins.

Hey @Luketina,

I tried to check your website but I don’t see any header duplication on the front end, would you mind sharing more information on how we can replicate it? Just want to let you know that I am not able to log in to your website due to Wordfence limit restriction.

Thank you.
