That wiki probably requires you to be autoconfirmed before you can make any edits. You should automatically be added to that user group 4 to 5 days after you register your account. This editing restriction causes confusion fairly frequently (here is another recent thread about the exact same thing).

The most common reason some wikis have this requirement is to protect against spam and vandalism. Quite frequently, spammers/vandals will typically edit either anonymously (relying on IP address changes to avoid blocks) or with a newly registered account (either to appear more legitimate or because their previous account has been blocked). Fortunately, those in charge of catching and reverting such activity can typically do so within 24 hours. However, if the vandal is a bot, there is still a lot of things they can do in that time. By restricting edits to autoconfirmed users, wikis avoid the risk of vandalism from anonymous users and mitigate the risk from registered users.

This restriction is typically enabled at the discretion of the local admin(s) but can sometimes be enabled by Wikia staff. Typically, the latter happens if the wiki has a high chance of being viewed by minors (people under 13 years old).
