Some pages that have been vandalized repeatedly are
semi-protected, meaning that editing by new or unregistered users is prohibited through technical measures. If you have an account that is four days old and has made at least 10 edits, then you can bypass semi-protection and edit any semi-protected page. Some pages, such as highly visible
templates, are fully-protected, meaning that only
administrators can edit them. If this is not the case, you may have been
blocked or your IP address caught up in a range block.
