This is brilliant! Thanks very much.

This is great. Solves so many hassles and works right out of the box. Thanks!

Works great, as expected. I hope WordPress will fix it soon, so we won't need these fixes anymore!

Thank you @eteubert!

Can't believe wpmu doesn't support this already. Thanks a ton!

Thanks a lot! Work out of the box.

Here is a new error that I am getting:

Your password reset link appears to be invalid. Please request a new link below.

You saved my day buddy. Working just perfect. Thanks :)

Awesome!

It still shows the Network Title in the email subject, like this: "[My Network Title] Password Reset". Do you know how to change it so it uses my site's title, and not the network's?

Works great - thank you!!

Hi, thanks for this!

For those who install WordPress in a separate folder (https://codex.wordpress.org/Giving_WordPress_Its_Own_Directory), you should use:
return str_replace(network_site_url(), get_site_url().'/', $message);
instead of return str_replace(get_site_url(1), get_site_url(), $message); (line 37)

WP is throwing a parse error after trying to activate the plugin: "syntax error, unexpected T_FUNCTION on line 13".

Using WP Multiuser 4.7.2.

UPDATE Mar 7, 2017 - Bug solved

Added this line to my htaccess file:

AddHandler application/x-httpd-php55 php

Works like a charm, thanks!

WP multisite 4.8.1

You should replace the hard coded site id on line 37 get_site_url(1) with get_network()->site_id to make:

return str_replace(get_site_url(get_network()->site_id), get_site_url(), $message);

in case the main site is not id 1

This works great on the "lost password" link underneath the log in details, however, if they type in an incorrect password... the error box shows with the link saying... forgotten your password... click "lost your password" to change it. This link (that appears in the error box) is still taking them back to the main site and not the sub-site that was intended... any thoughts?

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?
