Wordpress website keeps loading the maintenance page

Question

I was developing a new WordPress website so i added this function at the end of the "functions.php" file to redirect all users to a /maintenance-mode page in my website except me(My IP-Address):

function wp_maintenance_mode() {
    if ( !is_page( 2075 ) && $_SERVER['REMOTE_ADDR'] != "111.222.33.44" ) {
        wp_redirect( home_url( 'maintenance-mode' ) );
        exit;
    }
}
add_action( 'template_redirect', 'wp_maintenance_mode' );

After finishing the website development and i wanted to put it alive i have commented this function by putting it inside comments /* */ .. When i now access the website strangely the maintenance-mode still appears when i access any page. I tried to remove the comments but it still goes to the maintenance-mode page!

It is getting me crazy and i can't find why this happens. I searched everywhere, in the database, in my files for an access to the maintenance-mode page but i can't see any.

Do you have any idea what may be causing this?

Answer 1

I was able to fix it finally! .. All i did is deactivating all WordPress plugins then reactivating them again, and all worked fine .. Just that!!!

Answer 2

Have you tried to take the function out of functions.php file altogether? I had a similar issue, not with a maintenance function but a function I had in my code that wouldn't go away, I tried to comment it out as well.

I had to remove the function from the file, clear my cache, and upload the fresh file.

Once that was done - I added the function back into the file, commented it out and all is well!
