Try deactivate all plugins (How to deactivate all plugins when not able to access the administrative menus?) 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.

checking the logs I’ve found this error:
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…
any ideas why im getting these errors?

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);

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..
