WordPress login and password reset doesnot work, nor

Using phpmyadmin, check and repair the wp_users and wp_usermeta table.

Thanks,
Through wp-users and user meta on phpmyadmin, tried changing password. However, even the changed password did not work on wordpress admin. it still behaves the same way.
please help. its a daily update blog and i am struck since three days
My host is also unable to resolve it yet.

Did you check and repair the tables as I suggested? How did you try to change the password?

i went to wp-users and changed password, that is changed password and selected Md5 on function and saved it.
I could not repair database. I am sorry i am not that good with PHPmyadmin. can u please guide me how to repair the wp-users and wp-user meta tables. could not find any direct option there.

(And i dont have cpanel for this website JF additional info)
thank you

thank you Steve Stern for the tutorial. I did the check status of the tables and repaired the tables. Tables status are “OK” and no problem with it. But still the problem continues.

If you are correctly resetting the password *and* you still cannot login, I have to ask: Are you updating the right database?

yes, for sure. I have cross checked it on the wp-config file. Even my hosts tech support team too has confirmed it. even other wise i have only 3 databases there. I am 100 % sure its the right one.
thanks

So you select “MD5” and enter a password like “ABCDEF”. When you login, are you using “ABCDEF” as the password (correct) or the MD5 hashed value (incorrect). Sorry to ask such basic questions, but I don’t know a better way to debug this than to go to the basics.

Hmmm… you said “site redirects/refreshes the login page with no errors.” So you’re not getting a “bad login” message.

If you enter a random userid and password (ones you know don’t exist), do you get an error or the same redirection?

please feel free to ask any question, however basic it may be. i much appreciate this help. Need solve it at the earliest.

When i try logging in using wp-admin i give ABCDF- the non encrypted form. not hashed form.

Just to make sure that the password was changed for sure. I saved a password without MD5 encryption.(could see the changed password on the table) .
THe problem persists even after it.
thanks

when i try with random password, i get a password incorrect error message

OK, then let’s try a couple of things:

1. Use a different browser or a private/incognito session (to eliminate browser caching)

2. This may be a plugin or theme conflict. Please attempt to disable all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles.

See https://www.wpbeginner.com/plugins/how-to-deactivate-all-plugins-when-not-able-to-access-wp-admin/

tried it and worked.. thanks a lot.
i renamed plugin folder in file manager to deactivate it.
After that i tried opening in incognito browser
it opened, initially junk letters came instead of my language on all posts.
i got following error messages on it.
