    Hello there, when I wan’t to use this plugin, I getting error with below message:

    Another plugin has already overridden the password hashing mechanism. The “PHP native password hash” plugin will not work.

    But, I don’t install any another Password Hashing plugin in my WordPress, and the password queries (that I see on phpMyAdmin, and in the user_pass column) are same as WordPress Formats, like $P$Bx.7WPgzxxxxxxxxx.Gxxxxxxxxxxx or $P$Bp1xxxxxxxxxxxxxxxxx/xxxx/.

    What should I do for fix this problem? And, can you fix this issue?

    Thank You ^_^

    Hi Farrel,
    I’m sorry about the late reply. I should subscribe to this plugin support forum.

    WordPress’s swappable password mechanism that this plugin uses is not quite robust. This warning is triggered if a function that this plugin is about to declare is already declared.

    If you still have this problem, I could use these information:
    – How did you install this plugin? It supports composer-based installations as well. Did you install it from a zip file/admin UI?
    – Can you search your code base for a function wp_check_password ? This is the function declaration that we are trying to override. WordPress core has one, and this plugin proposes the new password hashing mechanism by declaring the exact same function names. There are not many plugins that override password backend, but this search will reveal all instances.

    Ok, it’s fine, just relax 😀

    1. I install it from admin UI, not from ZIP File.
    2. How to search my Code base for a function? If you mean is my base code in my theme function.php, I think the function wp_check_password function is not exists in my theme function.php file. If not, how to search for this function?

    But, if you mean wp_check_password function in wp-includes/pluggable.php. There is my WordPress Default code: https://gist.github.com/FarrelF/7348f027efbf2da1d6056934f34aa0f4
