This means exactlt what it says: you have a plug-in that is not compatible with your version of FCP and/or macOS.


Did you ever have mO2 installed on your mac?


Did you recently update FCP and/or your OS?


I don't think that this plug-in has a compatible update, but check with the manufacturer.

In the meantime, close FCP, and look under


/Library/Plug-Ins/FxPlug


or


~/Library/Plug-Ins/FxPlug


and see if there is a "Separator" folder there.

If so, move it out of the folder; park it somewhere temporarily, in case you are not ready to get rid of it completely; then start FCP again.
