When it comes to local issues, staff involvement should only be as a last resort. Local administrators and community members are going to be the most knowledgable about the culture and users of their wiki, as well as the specific issue on the wiki. To that end, local communities are best equipped to resolve local disputes.
If you do need to contact Wikia, please include as much information about the issue as possible. For example, if there is a problem with other users, please explain the dispute between the users and what the local community and admins have already tried to do about it. Reports about inappropriate content should have the URL of said content included. Features that cannot be enabled or disabled through Wiki Features can also be requested.
In the case of reports about bugs on the wiki that are not the result of local changes, please send them to Special:Contact/bug. Also remember to include as much information as possible. Screenshots and information about what browser and the version of the browser you are using are all incredibly helpful.
