NGFB Warning: Image rejected

Hello,

since the update I have a big problem.
Every single image I insert into a post is now rejected because of size issues, that I don’t understand.

e.g.

NGFB Warning:

Media Library image ID 678 rejected – the resulting 200×143 image for the “Open Graph Image Dimensions” option is smaller than the hard-coded minimum of 200×200 allowed by the Facebook / Open Graph standard.

The problem is, that the original size of the image uploaded is 700×500.

I get this warning every single time, no matter what size the images originally has.

I don’t really know what the problem could be…

Can you help me please?

Thank you! 🙂
