Multisite install not working

Hi

I know this is a topic that others have posted about, but I have tried everything I could find and am still having the same issue.

I am trying to set up a multisite. I followed the steps as described but can’t seem to get past the network install page where it comes up saying “Warning: An existing WordPress network was detected”.

After the first time I tried, I read that I had to delete the .htaccess file, remove all added lines from wp-config.php and delete the following lines from the database;

drop table wp_blogs;
drop table wp_blog_versions;
drop table wp_registration_log;
drop table wp_site;
drop table wp_sitemeta;
drop table wp_signups;
alter table wp_users drop column spam;
alter table wp_users drop column deleted;

Once this is done, I re-log back in and confirm there is no “Network Setup” menu option. Then I add the ALLOW_MULTISITE line to the wp-config.php file, log out and back in and navigate to the “Network Setup” menu. I click Install and am presented with the code to insert into the .htaccess file and wp-config.php as follows

define(‘MULTISITE’, true);
define(‘SUBDOMAIN_INSTALL’, true);
define(‘DOMAIN_CURRENT_SITE’, ‘laurencesymonds.co.uk’);
define(‘PATH_CURRENT_SITE’, ‘/’);
define(‘SITE_ID_CURRENT_SITE’, 1);
define(‘BLOG_ID_CURRENT_SITE’, 1);

and

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ – [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule . index.php [L]

placing the .htaccess code between the <IfModule mod_rewrite.c> and </IfModule> tags in that file.

No matter what i try after that, I always come back to the “Network Setup” page as described.

Does anyone have any other suggestions I could try?

Many thanks
