my moodle verison is 2.5.2. On my administration block, The links having dropdown menu items are not working. (i.e users, courses, grades..) But 5 links having the settings icons (i.e. notifications, registration, advance features..) are working. In a couple minutes ago, I completedly remove my navigation block. Is there any relationship between removing navigation and administration links? how can I fix this?
In the picture, the rec circles are non working links. green circles are working links.
