cant login (password is incorect) everytime i migrate to classicpress

classicer · May 16, 2025, 1:27am

Expected behavior

after migration, i should be able login to my site as usual without additional steps

Current behavior

everytime i migrate my wp to classicpress, i cant login, it always says password is incorrect.

Possible solution

i tried to change my password using phpmyadmin, but it doesnt work. the only solution is change password using wp-cli, it works eventough I use same username and password as before. but, thats not the main issue here.

Steps to reproduce

all my website is using cyberpanel, and I think maybe problem is theme or plugin. So, I make new website, kilat.my.id, with fresh install. I use these plugins and themes on kilat.my.id

but the issue remains the same

Context

My main issue is I want to move my other website. This website is news website with many editors. It is very hard if I must reset password one by one with WP-CLI.
I want to know what the problem is, and I hope I can migrate without having to reset passwords. Thank You

Welcome to ClassicPress. There should be no need to change password when migrating to ClassicPress.

But a thought has just struck me. WordPress just changed their login system for version 6.8, so I wonder if that’s the issue. But even if it is, once you’re on CP and have logged in once, that should fix the problem once and for all

Thank you,
I try reproduce the issue.
I switch back to WordPress, in WordPress i can log in like normal.
In WordPress, I make 5 users, user1 to user5. Then I migrate to ClassicPress.

In ClassicPress, the same problem comes back. I cannot log in.
Then I reset the password for user1 with WP-CLI, and then i can log in using user1.
I try to log in with user2 and the others, but I still cannot log in.
I can only log in if I reset the password with WP-CLI.

maybe the problem is solved if i reset one by one using wpcli, but i have so many user in my news site. i hope there is solution without reseting password.

I think @timkaye might be correct when he says the difference in login system might be it. I will try to reproduce this afternoon. If this is it I think we need to have a discussion on how to solve the issue for sites having many users.

We have now verified that it is indeed WP’s new login system that is the cause of this problem, and we are now testing a solution.

Thank you. I’ll wait for the result

This issue should be fixed with the following proposed code change:

## Description As discussed in the core meeting today there are migration issue…s now between WordPress 6.8.x and ClassicPress due to a different approach to password hashing. This PR aims to address this issue and also close #1946 Changes broadly covers three things: 1. Any password set in WordPress 6.8 using the default configuration should now allow login after migration to ClassicPress. 2. Resetting a passord to an `md5()` hash in the database will now allow a user to login, this restore a lockout workaround often recommended in online articles about adding such a hash directly into the database tables. The above change also fixes #1946 4. In test the above I noted that any legacy passords that start wit `$P$` are not detected as needing rehashing, this is because `$wp_hasher` is not empty after checking these passwords so `wp_password_needs_rehash()` returns early. ## Motivation and context As per Core meeting, migrations between WordPress and ClassicPress should not lock users out of their sites and migration should be easy in both directions. For further development, ClassicPress may want to consider a password hash prefix in the database like WordPress uses. I tried this but it seems a lot of PHP unit tests will need review if this approach is taken. ## How has this been tested? Lots of local testing so far, but needs more user testing. ## Screenshots N/A ## Types of changes - Bug fix

Thank you, it works now.
I installed WordPress 6.8.1 again and migrated to cp using the CP Migrate plugin.
At first, I could not log in.
So, I changed the pluggable.php file in the /wp-includes/ folder.
I downloaded the file from this link:

github.com/ClassicPress/ClassicPress

src/wp-includes/pluggable.php

515d14802

<?php
/**
 * These functions can be replaced via plugins. If plugins do not redefine these
 * functions, then these will be used instead.
 *
 * @package ClassicPress
 */

if ( ! function_exists( 'wp_set_current_user' ) ) :
	/**
	 * Changes the current user by ID or name.
	 *
	 * Set $id to null and specify a name if you do not know a user's ID.
	 *
	 * Some ClassicPress functionality is based on the current user and not based on
	 * the signed in user. Therefore, it opens the ability to edit and perform
	 * actions on users who aren't signed in.
	 *
	 * @since 2.0.3
	 *

Now, all users can log in without problems.

A plugin was added to ClassicPress Directory as a temporary fix for anybody having this issue.

classicer · May 28, 2025, 8:39am

Thank You, I have tried it. Make sure the plugin is downloaded and activated before moving to CP. Then, run the CP migration plugin as usual. After that, there will be no more login issues.
