 * [15 years, 6 months ago](https://wordpress.org/support/topic/network-mulisite-installation-errors-help/)
 * i’m pretty new at this and i would appreciate any and all help i can get.
    after
   adding
 * define (‘WP_ALLOW_MULTISITE’, true);
 * to wp-config.php successfully create “network” option under tools, everything
   appears to work correctly.
    (however if i attempt to log out at this point receive
   a page full of these errors: Warning: Cannot modify header information – headers
   already sent by (output started at /home/design/public_html/wp-config.php:1) 
   in /home/design/public_html/wp-login.php on line 337 )
 * other then that everything appears normal
    i proceed to network install, sub 
   directories create blogs.dir in wp-content add:
 * >  define( ‘MULTISITE’, true );
   >  define( ‘SUBDOMAIN_INSTALL’, false ); $base 
   > = ‘/’; define( ‘DOMAIN_CURRENT_SITE’, ‘designquoter.com’ ); define( ‘PATH_CURRENT_SITE’,‘/’);
   > define( ‘SITE_ID_CURRENT_SITE’, 1 ); define( ‘BLOG_ID_CURRENT_SITE’, 1 );
 * to wp-config.php above “thats all happy blogging”
    then add
 * >  RewriteEngine On
   >  RewriteBase / RewriteRule ^index\.php$ – [L]
   > # uploaded files
   >  RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-
   > files.php?file=$2 [L]
   > # add a trailing slash to /wp-admin
   >  RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin
   > $ $1wp-admin/ [R=301,L]
   > RewriteCond %{REQUEST_FILENAME} -f [OR]
   >  RewriteCond %{REQUEST_FILENAME} -d
   > RewriteRule ^ – [L] RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*)
   > $2 [L] RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L] RewriteRule . index.
   > php [L]
 * to .htaccess file..
    click login again, brings me to the login page with these
   errors on top

   at /home/design/public_html/wp-config.php:1) in /home/design/public_html/wp-login.

 * followed instructions under How do I solve the Headers already sent warning problem?
 * still getting the same errors..
    there doesn’t appear to be any whitespace on
   line :1 of my wp-config.php file or at the end. i also have not edited/modified
   anything from original download other then adding install lines for network. 
   wp-config.php begins with <?php and ends with ?> with no white space
 * could there be any other reasons for these errors?

 * … added spaces between each line of the code to create super admin just to try,
   and it worked some how.. i didn’t see any info anywhere that backs up that fix
   but that’s what happened. thanks for the help!!
