There may be a Chrome-related bug in the new BB 1.6.3.3 update. I noticed that after I installed it, the RSS feed icon in my site’s footer become invisible. The icon still registers as being there with a mouseover, but it’s invisible. This happens only in Chrome. The icon shows up correctly in Safari and Firefox.
It looks like wpbeaverbuilder.com is having the same issue. When I view your site in Chrome, I see a generic square box for your Facebook footer icon, and your Twitter icon is invisible. Those icons appear correctly in Safari and Firefox.
I checked our site using Chrome on both Win7 and Win10 machines and I am seeing those icons just fine. What platform were you on when you checked the site?
