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
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.
