error 404 when I try to login as admin

I installed a login/register plugin, and did some setting. And now I can’t get to the /wp-admin page,

what happens if you disable this plugin?

Like I said, I can’t even login and get to the dashboard, so I can’t disable the plugin which I think is the problem.

You will need to FTP into your web hosting account and find the /wp-content/plugins directory for your site. Once you are in there, you can change the name of the folder for the plugin that you installed and it will deactivate the plugin which should allow you to log back in again.

How do I do that? I use hostgator

You would have to look at your email that you received when you signed up for your account. Then with that info, use an FTP client such as FileZilla to log into your server and make the changes.

You can also try logging to cPanel if your account has it. Try going to https://yourdomain.com/cpanel and if it asks you for login info you’ll most likely again need your hosting account setup email (try entering in the login info provided within that email). Once you get logged in you can use the File Manager to browse to the wp-content/plugins directory and rename the folder in there.

Thank you so much, it worked. I did like you said, then just removed the plugin. Thanks. ??

@ JarretC Member can you tell me which username & password i should use for log in cpanel.because i can not log in my site cpanel with my site username & password.

ripokumar you would have to contact your web hosting provider or look for the email that they sent you when you first signed up with them.

That email should contain the appropriate information to log into your cPanel account.

@ JarretC thank you very much.

I installed wordpress cpanel, there are 2 versions of 3.2.1 and 3.2.2. I delete it without my backup version 3.2.1. But then I can not get into wp adm and 404 error appears. Please help to restore it.
