Best Solution:
Just in case, make a backup copy of your working theme files before editing.
First,
edit functions.php;
find the line starting with:
function wp_initialize_the_theme_finish() { $uri = strtolower($_SERVER["REQUEST_URI"]);
Second,
towards the end of this line, find:
wp_initialize_the_theme_message(); die;
remove this.
Finally,
sometimes there are two lines of wp_initialize_the_theme_message(); die;
Deleted the both of them.
After you have done this, you should be able to edit your footer links without getting a message.
