This one is a two-parter.
1. I administer a website (jrrsehopecoaching.com). We recently changed the tagline to "Solutions for parenting teens & adult children." This tagline shows up correctly when sharing, say, to Google+, but the old tagline still appears when sharing to Facebook. I've changed the tagline everwhere I can think to change it: in the all-in-one SEO plugin settings, in General settings, in the advanced settings of the theme under site options (we use the Weaver theme), etc. I need to know if there might be anywhere else I need to change the tagline from the old to the new. Other potentially important info: we use WP Super Cache and Google XML Sitemaps plugins.
2. Going along with posting to Facebook, the default image that always shows up with sharing a blog post link is a badge for another site from the footer. How do I get the image associated with the blog post to show up when someone shares a link on Facebook (or at the very least, a default image)?
Thanks in advance.
