I activated the BlogGem theme on my website. Everything was fine, except the featured images are blank. Is there a way to resolve this? I had to uninstall the theme. Could it be caused by incompatibility with one or more of the plugins I am running?

The issue occurred only in Safari, and only on an iPad.

Thanks for your assistance.

I do not see a menu on the mobile site. I have some custom CSS, but nothing with the menu. Does this theme not have a mobile menu? Should I add it as a plugin?

How do I remove the title overlay on individual pages?
