I did a blunder yesterday with my site while trying to do some coding thing in functions.php files, I am explaining below what I did exactly kindly see if anything could be done.
I am using dazzling theme and yesterday I was trying to remove footer text “theme by colorlib powered by wordpress” and in the process I installed and activated dazzling child theme then under appreance>editor in functions.php file and css files I pasted some codes which were mentioned in one of the thread at support forum of dazzling and clicked on update file but nothing was happening to that footer text so I deleted those codes and clicked on update files again and logout from wordpress admin, since then I am not able to see my site.
When I type my url it shows below screen, can’t even login to wp-admin, it shows
“Warning: Cannot modify header information - headers already sent by (output started at /home/digitalfreshers/public_html/wp-content/themes/dazzling-child/functions.php:21) in /home/digitalfreshers/public_html/wp-includes/pluggable.php on line 1167”
Kindly help at earliest.
