I have used Frontier theme on a few sites and don’t have this issue on any of my other sites. Of course, it has been a while since I have worked on those other sites, so I may have forgotten about some setting. That’s why I write. The site in question is http://www.libertyeconomics.com and as you can see my sidebar widgets display on the main home page, but if you go to any of the individual post pages the sidebar widgets disappear. I know some themes you have to enable sidebars on posts and pages and so forth, but for the life of me I can’t find a setting to change to correct this.
I suspect it’s either recently edited files or added/updated plugins.
Check the part on your comment section that says:
“To use solvemedia you must get an API key…”
It might have something to do with that because that’s the last element showing.
