WordPress Network install error

Reinstalling wordpress multisite

Warning: an existing wordpress network was detected.

I tried multiple solutions including dropping tables, resetting .htaccess and completely resetting wp_config. It installs fine the first time but when I log out and log in I get this error.

Follow the steps in this order

1) Reset your wp-config.php file back to its original state, remove any MULTISITE references

2) Delete the .htaccess file or move it temporarily

3) Drop the following tables from your DB, use a tool like phpMyAdmin if you are not comfortable directly modifying table data

• wp_blogs
• wp_blog_versions
• wp_registration_log
• wp_site
• wp_sitemeta
• wp_signups
• wp_sitecategories

4) Log out and Log back into your site and initiate the Network Setup.

5) Recreate the .htaccess file with the copy pasted data

6) Modify the wp-config.php file, remember to paste those lines above the line where it says

/* That's all, stop editing! Happy blogging. */

Step 6 is important see below :
