 * Hi,
 * I’m working on a wordpress install locally, everything has been going fine until
   recently when I tried to login into the admin panel. I fill in my login details
   and press the login button only to be sent to a blank white screen. It goes no
   further and I do not know why.
 * In the address bar it’s [http://localhost:8888/icomprint/wp-login.php](http://localhost:8888/icomprint/wp-login.php)
 * does anyone know why I might be getting this? I can no longer access my admin
   panel and so I cannot make any more changes..
 * Please help
 * Warm regards
 * O

 * Try deactivate all plugins ([How to deactivate all plugins when not able to access the administrative menus?](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F))
   then if you can login, activate plugins one-by-one to find the culprit.
 * Could also be a lack of PHP memory —
 * Methods for increasing the amount of memory a PHP script may consume
 * 1. If you have access to your PHP.ini file, change the line in PHP.ini
    If your
   line shows 32M try 64M: `memory_limit = 64M ; Maximum amount of memory a script
   may consume (64MB)`
 * 2. If you don’t have access to PHP.ini try adding this to an .htaccess file:
   `
   php_value memory_limit 64M`
 * 3. Try adding this line to your wp-config.php file:
    `define('WP_MEMORY_LIMIT','
   64M');`
 * 4. Talk to your host.

 * The error logs for your server may indicate the problem, also. White screens 
   can be internal errors such as issues with config.

 * Cannot modify header information – headers already sent by (output started at/
   Applications/MAMP/htdocs/icomprint/wp-content/themes/icomprint/functions.php:
   446) in /Applications/MAMP/htdocs/icomprint/wp-login.php on line 314
 * the functions.php is the one used in the kubrik theme.. and line 314 is a css
   style for the header…

 * I’ve deleted the css styling that effected the header and now I get a similar
   error but it’s pointing to a pluggable.php file in the w-includes, here is the
   error:
 * PHP Warning: Cannot modify header information – headers already sent by (output
   started at /Applications/MAMP/htdocs/icomprint/wp-content/themes/icomprint/functions.
   php:417) in /Applications/MAMP/htdocs/icomprint/wp-includes/pluggable.php on 
   line 868
 * line 868 is the following:
 * header(“Location: $location”, true, $status);

 * any ideas on this?
 * I have deactivated the theme and I can now access the backend, so it’s something
   to do with the theme I’m working on..
