It didn’t work
I got this message:
Your PHP code changes were rolled back due to an error on line 2498 of file wp-content/themes/enfold/functions-enfold.php. Please fix and try saving again.
Cannot redeclare ava_auto_click() (previously declared in wp-content/themes/enfold/functions.php:720)
OK I found where the header was in appearance but I cannot change the link for the blog. There is no option to do so.
