4.5 causes infinite redirect on static front page

I’m having the same problem after upgrading to 4.5. I’m redirecting the to a subdomain for logged in admins, to get around some caching issues to do with CloudFlare CDN, ModPagespeed, etc. Since upgrading, this is no longer working on my static front page.

https://www.example.com redirects to admin.example.com when a user is logged in. This works for all pages except the homepage, where a redirect loop between https://www.example.com and admin.example.com causes infinite redirects.

It’s the changes on line 175 in wp-includes/canonical.php that are causing this issue.

-		} elseif ( is_page() && !is_feed() && isset($wp_query->queried_object) && 'page' == get_option('show_on_front') && $wp_query->queried_object->ID == get_option('page_on_front')  && ! $redirect_url ) {
+		} elseif ( is_page() && !is_feed() && 'page' == get_option('show_on_front') && get_queried_object_id() == get_option('page_on_front')  && ! $redirect_url ) {

Same problem here, not fixed in wordpress 4.5.1. Removing the redirect_canonical filter solves the problem, but is not optimal for SEO reason.

Had the same issue, 4.5.2, thank you so much for pointing it out @julianm

Like Motaz Shazly, had the same issue with 4.5.2 (was using 4.5.1 on which this issue did not occur). Reverting the line back fixes it for me. Thank you @julianm

I was able to get this fixed without hacking core using the following:

function disable_front_page_redirect_madness($redirect_url) {
	if( is_front_page() ) {
		$redirect_url = false;
	}

	return $redirect_url;
}

add_filter( 'redirect_canonical', 'disable_front_page_redirect_madness' );

Thank you Andrew for posting your solution which does not require editing the core.

I had the problem in 4.5.2 and fixed it by editing wp-includes/canonical.php because it needed to be fixed immediately. But then an upgrade to 4.5.3 brought the problem back.

Disabling the canonical redirect on the home page should survive upgrades.

And maybe WordPress will eventually fix the bug?

Not unless you let WordPress know.

Andrew, where did you put your code to make to work?

Hi Ms_Evette,
You can put the code in functions.php of your theme or create a plugin out of it.

Hi there, i think i have the some issue here after an update from 4.4. to 4.5.3.
All Links to pages are redirected to the landing page. The<a>-Tags have the correct links (domain.com/pagename/) , but i get all the time redirects to the landing page (domain.com).
Can anybody help me with that or knows about the Problem?

Hi flofas,
See my code snippet above and place it in functions.php and that should fix your issue. Let me know if it helps.

Hello all,

I just downloaded wordpress 4.5.3 and i have problem accessing to wp_config.php to setup the blog. It keeps redirecting me to the front page. Am wondering if you guys know what’s wrong? I really have no idea…

Hi Andrew,

I copied and pasted your code at the end of the functions.php file of my theme and nothing changed. Thank you for trying.

Thanks Andrew! That helped me a lot.

Today was a day when I begun meeting with nginx and I came across this bug what made me think that I won’t be able to use nginx but you actually saved me. Thanks again! ??
