[Solved myself!] Featured Images completely missing

Hello, The featured Image option for the portfolio projects is missing on the portfolio editor page. It is also missing on the screen-options tab, i can’t turn it on or off… Any idea? (turned off my other plugins… no results)

[UPDATE: Solved! There is more than the eye can see… corrupt plugin! checked the plugins folder (FTP) and there it was… but hidden in the admin area.]
