    I am unable to log in to my wp-admin account. After entering my user name and password, the login page comes back with a window saying “ERROR: Cookies are blocked due to unexpected output. For help, please see this documentation or try the support forums.” Also, the top of the page says the following:

    Warning: Illegal offset type in isset or empty in /nfs/c04/h02/mnt/66348/domains/gesw.com/html/wp-content/plugins/jetpack/modules/protect/shared-functions.php on line 183

    How can I resolve this? I need to login to the admin console to add some information. Thank you!

    Thanks for that information! I see some different errors on your wp-login.php page:

    The reason for the error in WordPress is that one of the active plugins or files like functions.php or any other theme file produces unexpected output, that results in a “headers already sent” warning.

    Get your server’s error logs and check them for the date you started to get the error. You’ll be looking for something like: Cannot modify header information – headers already sent by (output started at”) – if it is Jetpack, log in to your site via FTP, and delete the existing jetpack plugin files. Once you have done so you should be able to install Jetpack again via the Plugin installer in your dashboard.

    Let me know if you still have this problem and I’ll be happy to take a closer look.

    Hi, csonnek

    Thank you very much for stepping in. I just went to my Media Temple web host account and discovered that the settings for the server error logs were set to “disabled”, so I am not able to check anything. I changed the setting to “enabled” but that will not help me out this time.

    Is there any other way to find out what plugins I can delete by FTP in order to be able to access my WP admin console? I appreciate any help you can provide.

    It may be germane to tell you that back in March I updated WP and something in the update “broke” our site, so I replaced everything with my previous backup from December of 2015. Everything looked good then up until a few days ago when I wanted to add some media to my site and have not been able to log in.

    Thanks again,

    Miguel

    You should be able to enable the logs and try to login again to trigger an error.

    Also, you shouldn’t need to delete anything – you can simply rename the plugin folder to something else to “disable” it. For example: you can rename the jetpack folder to temp_jetpack or something similar to disable the plugin. You can do the same with all the other plugin folders you have.

    Although the errors on our website all say Jetpack, on our web server the only error that refers to wp-admin is this:

    [Fri May 13 06:10:22 2016] [error] [client 24.240.23.18] ModSecurity: Warning. Match of “rx ^POST$” against “REQUEST_METHOD” required. [file “/etc/apache2/mod_security/custom/wpbrute.conf”] [line “14”] [hostname “gesw.com”] [uri “/gs-bin/php-stable/wp-login.php”] [unique_id “VzXSPEgv5BgAAEwO@kEAAAA3”]

    I’ll see if I can figure out what that means, but not being a programmer, or even a real IT guy, I don’t know how far I’ll get. Any further help would be most welcome!

    Well, I ignored the previous error messages and disabled Jetpack through FTP. Now I’m logged in to the console! Thank you, csonnek, for your help. Now I’ll see what other trouble I can get into…

    Thanks for the update! Based on that modsec error, you might want to check with your host to see why ModSecurity is blocking things there.

    Let us know if you still have trouble once you get Jetpack up and running and I’ll be happy to help! I’ll mark this resolved for now, but you can still respond to it if you still need help.
