Thread:Project:Support desk/Wikisysop cannot grant rights to users (to make them bureaucrat or administrator, both of which groups Wikisysop is in)/reply

To be able to access the page Special:Userrights your account must be in a group, which has the "userrights" right set. You can check this by having a look at Special:ListGroupRights, where you have a list of the rights which each group has. Missing rights can be added in LocalSettings.php as explained here. Adding

should do.
