WordPress Multisite Troubleshooting

Setting A Network Super Admin

WordPress websites with Multisite enabled have a lot of extra user roles in place. If the user you log in with does not have the menu options "My Sites" > "Network Admin" (or similar) they won't have full access to making updates and adding plugins. To resolve this you can do one of the following:

1. Log in to the current Network Admin account assign Network/Super Admin privileges to the desired account.

2. Access the database directly. Navigate to the wp_sitemeta table. Find the row labelled "site_admins" and make the following update.

a:1:{i:0;s:12:"currentadmin";}

to

a:1:{i:0;s:7:"newadmin";}

with the names "currentadmin" and "newadmin" being updated from the old user to the new user respectively. Also, very important, The number directly before the username (e.g. 7 for newadmin) must be the number of characters in the username (4 for "name", 7 for "newadmin", 31 for "iwonderifthyisusernameistoolong", etc.). I don't know why this is a rule, but it won't work otherwise.
