The Twitter, Pinterest, and email share buttons seem to get hung up on special characters in the meta text. I’m setting the meta description with Yoast SEO, but it still does not work if I disable Yoast. I tried disabling all the plugins except Unyson, as suggested, and had no luck fixing it. I also disabled the child theme and used the straight Jevelin theme (version 2.8.1) instead, with and without plugins disabled, and no luck.
