Error on og description

version: 2.3.4.

I tested my site with facebook open graph debugging and finding an error
in the og: description.

I made you a screen shot of the error.

I think that simply lacks “%”.

Can you kindly check the free version of your plugin with a new
installation, not upgrade, and check this error and if fix?

Thanks a lot
