It looks to be because you were trying to name the wikia with "wiki" at the end. You should have gotten a warning message, like "This wiki name contains a word that violates our naming policy".

If you want to create a wikia, for example My Dog Wiki, name it as mydog.wikia.com, not mydogwiki.wikia.com and you should have no issues.
