Memory Limit Problem

Im receiving the following error trying to access thru “/wp-admin/” and the only way I can go back to the dashboard is deleting the wp-config.php and redoing install.

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 491520 bytes) in /home/rcfgprev/public_html/wp-includes/js/tinymce/langs/wp-langs.php on line 222

Also tried increasing memory limit in the default-constants.php like this:

if ( !defined('WP_MEMORY_LIMIT') ) {
		if( is_multisite() ) {
			define('WP_MEMORY_LIMIT', '128M');
		} else {
			define('WP_MEMORY_LIMIT', '64M');
		}
	}

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

With no avail…
