});

It works without this plugin but having redirect to main site, it means reset password function works fine without using this plugin but to solve url redirection to related subdomain I'd like to use this plugins so after activating the plugin, I'm getting the following error:
The email could not be sent.
Possible reason: your host may have disabled the mail() function.

PHP 7.0.25
Wordpress multi site version: 4.9.1-0
Server: Debian 9
Mail: SendGrid

Any idea how to fix this?

Hello. Great plugin, but I can confirm mehranhzh's issue. As of the current WP version 4.9.6, something seems to have changed in how Wordpress works that breaks its "drop in and go" functionality. Mail is correctly setup sending email with no problem until I activate this plugin. I get the same error:

The email could not be sent.
Possible reason: your host may have disabled the mail() function.

Does this error reference the PHP mail() function? wp_mail() function? Or is it talking about linux mail command?

Thanks!

on my multisite installation this plugin doesn't work. I try it in different ways..per functions.php as a plugin and as mu-plugin. but no luck
please help thx

Works great for me on WordPress 5.x Just added to sunrise.php in /wp-content/, with the mod from https://gist.github.com/eteubert/293e07a49f56f300ddbb#gistcomment-2213197 (see above)

I unzipped then copied folder into my wpmudev host account: pe1.wpmudev.host NOTE: I did rename the folder to:
/site/public_html/wp-content/mu-plugins/Password Reset on Local Blog
Unfortunately, it has no effect for me, on my prod site (hosted on wpmudev) or on my dev site (LocalByFlywheel on my PC). Could the problem just be the misspelled word "passwort" in the Plugin Name and Description?

Why don't you publish to the official repository?

@davidperezgar I unfortunately have no time to maintain yet another plugin

Ok ;)

Nice fix! 👍

Thanks!

Awesome snippets. It works well except 2 things: with Buddypress, they force another email and the link in it redirects to the main site. If I deactivate Buddypress (buddy boss), it works again. Second, there is a Site Name mention in the email shared to the user that is in my case always the main site. Except for thee 2 points, it works like a charm. Kudos!

Great, it was just what I needed! A small suggestion for the last lines, for websites that are in other languages:

// fixes email title
add_filter("retrieve_password_title", function($title) {
	return sprintf( __( '[%s] Password Reset' ), wp_specialchars_decode(get_option('blogname'), ENT_QUOTES) );
});

Is it just me or this has stopped working now?

If you want to change the email body message so it does not say the main site here is the code for that to replace the existing line 35:

// fixes URLs in email that goes out.

add_filter("retrieve_password_message", function ($message, $key, $user_login, $user_data) {
	$message = __( 'Someone has requested a password reset for the following account:' ) . "\r\n\r\n";
	$message .= get_option('blogname') . "\r\n\r\n";
	$message .= sprintf( __( 'Username: %s' ), $user_login ) . "\r\n\r\n";
	$message .= __( 'If this was a mistake, ignore this email and nothing will happen.' ) . "\r\n\r\n";
	$message .= __( 'To reset your password, visit the following address:' ) . "\r\n\r\n";
	$message .= network_site_url( "wp-login.php?action=rp&key=$key&login=" . rawurlencode( $user_login ), 'login' ) . '&wp_lang=' . $locale . "\r\n\r\n";

	if ( ! is_user_logged_in() ) {
		$requester_ip = $_SERVER['REMOTE_ADDR'];
		if ( $requester_ip ) {
			$message .= sprintf(
				/* translators: %s: IP address of password reset requester. */
				__( 'This password reset request originated from the IP address %s.' ),
				$requester_ip
			) . "\r\n";
		}
	}
  	return str_replace(get_site_url(1), get_site_url(), $message);
}, 10, 4);

@eteubert thanks so much for this plugin.

This plugin really saved my day. However for me it only works with Wordpress Default Login. I am using Paid Memberships Pro and would like to use PmPro login page (in my case named /login). There must be an easy way to tweak the plugin so that wp-login.php is replaced by /login/ in the lostpassword email? That would solve my issue. Secondly - this plugin seems not to work if Maintenance plugin is active.

@Av10ex - does it not work if you replace all the wp-login.php by login?

@Av10ex Not sure if you're still wanting/needing this yet or not... but I think I found a resolution via my forked version of this code at https://gist.github.com/KZeni/7760876c01ebb681ad439a452dc64427.

In effect, I just bumped the priority of the filters from 10 to instead be 12 as it appears (and maybe this is only when the Paid Memberships Pro [PMP] site is also on WPEngine hosting as is it in my case [since PMP then does its own URL adjustments to append wpe-login=1 to the assorted URLs to help with WPE hosting compatibility; which it seems my forked version works without it while on WP Engine [without needing to detect WPE within this gist to then selectively include it... one could also just hard-code the addition of that argument into the gist's $args if one knows the site will be on WPEngine for the foreseeable future] then just honoring the current site URL being viewed in the multi-site/network]) that this needs to happen after any number of adjustments being made to these URLs with a stronger priority than 12 (preventing them from being overwritten by reducing the number of filter[s] that might be remaining & come after this in priority.) Now, maybe the priority of 12 doesn't work for you, but this one change did seem to do the trick for my setup.

I also renamed "passwort" to "password" in a few spots (including the file name), made the URL that's sent out grab what it sees as the current site rather than still sending it as get_site_url(1) per line 37 of this original gist (as it is now; I just commented out the old line and added the new one below it on my fork), pointed it to my forked Gist for the URLs, and ran Prettier on the code.
