I inserted 2 images in the header of the page, linking to different languages in the page.
And when I try to insert a post I get this error:
Warning: Cannot modify header information - headers already sent by (output started at /home/web26255l/domains/svalner.se/public_html/wp-content/themes/propulsion/functions.php:1) in /home/web26255l/domains/svalner.se/public_html/wp-includes/pluggable.php on line 881
I changed some codes in the functions.php and then replaced it with a Backup that I had, could it be something wrong, ether? should I replace the functions.php with the original that comes with the propulsion zip file?
