Title: wp-admin not found error Last modified: August 19, 2016 --- # wp-admin not found error * [Te Calleja](https://wordpress.org/support/users/tecreative/) * (@tecreative) * [15 years, 9 months ago](https://wordpress.org/support/topic/wp-admin-not-found-error/) * hi everyone, * a few days ago, i was getting a 404 (not found) error when i go to my wp-admin. after searching the forum and google, i came across so many posts and suggestions, but none of them worked for me. i am enumerating them here, as it may work for some people searching for help on that error. here are the things i tried: * 1. cleared my cache 2. re-uploaded wp-admin 3. re-uploaded wp-includes 4. disabled plugins (via ftp by renaming plugins folder, since i can’t log in) 5. added code * ``` /** wp-admin login fix */ @define('ADMIN_COOKIE_PATH', '/'); ``` * to my wp-config.php file as suggested here [http://www.kinocreative.co.uk/hints-and-tips/wordpress-cant-login-to-wp-admin/](http://www.kinocreative.co.uk/hints-and-tips/wordpress-cant-login-to-wp-admin/) 6. changed folder permissions as suggested here [http://www.techzoomin.com/wordpress-login-issueswp-admin-showing-404-error-page/](http://www.techzoomin.com/wordpress-login-issueswp-admin-showing-404-error-page/) 7. checked my login file (among others) as suggested here [http://codex.wordpress.org/Login_Trouble](http://codex.wordpress.org/Login_Trouble) * i then discovered that i was able to log in using one of my other usernames that has editor role… but none of my admin usernames can log in. i went into phpmyadmin and replaced the wp_capabilities of my admin to make it the same as the editor— and i was able to log in! * not sure if this is a bug… around that time, i had already sought the help of my hosting provider, and they replied that there was a symbol lookup error of suhosin. they had resolved the issue on their side, and i was able to log in to wp-admin again. * anyway i hope this post helps others looking for a solution to that problem, and i hope someone can also look into that issue i encountered (able to login as editor, but not as admin) — if its really a bug, or just a hosting issue on my side. * thanks!

Will spend more time testing recent changes against suhosin soon. * [Gilligan](https://wordpress.org/support/users/playgod/) * (@playgod) * [15 years, 9 months ago](https://wordpress.org/support/topic/wp-admin-not-found-error/#post-1654517) * Frederick, I think this is more of a problem on Cpanel servers than elsewhere. I did not see this issue on my own server, which runs PHP in fcgid, not with suhosin. * I checked on the Cpanel forum and there are lots of issues with WP 3.0.1 administrator level users having issues with suhosin. * [Frederick Townes](https://wordpress.org/support/users/fredericktownes/) * (@fredericktownes) * [15 years, 8 months ago](https://wordpress.org/support/topic/wp-admin-not-found-error/#post-1654518) * I see.
