You could try disabling your antivirus program, refresh the webpage to see if the missing buttons appear then re-enable your antivirus as soon as possible.
Or.....if you have the 'browse' button, click that to choose your picture, then when the window to the left of the 'browse' button has the fakepath URL in it, move your mouse pointer to the right to where you feel the 'upload photo' button should be, and if your mouse pointer is a hand and not an arrow, click once.
