The "quick tags" plugin is what gives those buttons. If you don't have the buttons try switching to "expert" tab for when you write a post (hopefully that's all it is). If you have the buttons and they are not working try reloading the plugin with a weird symbol on the right side of the plugins page. Looks like a hollow dot and a solid dot connected by a black line. Dunno what it is supposed to be, but click it to disable then click it again to enable the plugin.
Or worst case get a brand new copy of the package, unzip it on your desktop, and upload only that plugin to your server.
