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 :

Just in case it helps anyone else, I was experiencing this error after I forget to manually clear my OpCache after making the changes to wp-config.php, so the database indicated a multisite network but wp-config did not reflect it. Clearing the OpCache fixed the problem.
