Hi!
Page starts correctly when entering https: // domain. If the page starts with https: //www.domain, the following error message will be displayed: “Can not modify header information – headers already sent by (output started at / www / htdocs / w00c9dc2 / wp / wp-content / themes / enfold / config -templatebuilder / avia-shortcodes / masonry_entries / masonry_entries.php: 56) in /www/htdocs/w00c9dc2/wp/wp-includes/pluggable.php on line 1223 ”
What should I do?
Regards
Morcy
Hey Morcy!
Please try adding following code to Functions.php file in Appearance > Editor
add_theme_support('avia_no_session_support');
Cheers!

Hello Victoria,
thanks for the help link.
I checked both files of the error message on superfluous whitespace and found none. Then I replaced both files with the same from a backup of September 2018 (at that time there was not the problem). The error message continues. Browser cache has been deleted multiple times. What next?
And why can I easily call the page without www?

Hi!
After activating the parent theme and then activating the child theme, the error message is gone. I do not know why …, but ok.
