Fatal allowed memory error on Wordpress MU

I am getting this error when logging into the backend of my Wordpress MU installation:

Fatal error: Allowed memory size of 268435456 bytes exhausted

I am also getting blank admin dashboard with I love into:
http://oversimplification.mvmt.com/wp-admin/

I submitted a request to my hosting provider PSEK and got this response.

It didn't work. The problem still is there.

----

Hi Rolando,

we've added following line to your public .htaccess file:

php_value memory_limit 512M

This should fix the issue, please try accessing the site now.

Please note that exceeding allowed memory size could indicate a memory leak or some other issue that require an experienced web-developer to have a look.

Scripts which hit PHP memory limit could overload the server - in this case we will disable the script or whole account.

Please let us know if you have any further questions or concerns.

-----

This has however not fixed my problem.

Can any of you help?

    It might be one of your plugins causing this, or your tempalte.
    Try to remove plugins from the wp-plugins folder (this will auto-deactivate them, if you don't have access to admin panel)
    Then check one by one who causes this.

    I log in and looks ok, maybe the changes takes some time or you need to refresh your browser cache

    Wordpress assigns the php_memory limit internally. You can try setting a higher limit to see if that helps. MU and resources intensive plugins are what usually cause this.

    Open the file /wp-includes/default-constants.php at the top you'll see,


    
function wp_initial_constants( ) {
    
	global $blog_id;
    

    
	// set memory limits
    
	if ( !defined('WP_MEMORY_LIMIT') ) {
    
		if( is_multisite() ) {
    
			define('WP_MEMORY_LIMIT', '64M');
    
		} else {
    
			define('WP_MEMORY_LIMIT', '32M');
    
		}
    
	}
    

    
	if ( ! defined( 'WP_MAX_MEMORY_LIMIT' ) ) {
    
		define( 'WP_MAX_MEMORY_LIMIT', '256M' );
    
	}


    Change the line below, 64M to 128M or 256M

    if( is_multisite() ) {
    
			define('WP_MEMORY_LIMIT', '64M');


    And see if that fixes the problem.

    add that line into your wp-config.php file. it shoud make it work...

    i DO NOT recommend altering core files. this will break on next update you make!
