Weta: Read More

Hi, after I’ve updated the Weta theme, if I put the mouse over the “read more” link, the text changes color and disappears from view, I’ve checked the Weta demo page and the read more link does not have the same behaviour. I do not have any plugin installed related to this. this is my test site for reference: http://www.bruhast.com/category/text/

thank you.
