I have a similar problem, but activating the plugin didn’t fix it. I updated from version 0.62 to version 0.66 and instead of displaying the posts, the page just displays the shortcode.
I tried the following
- Re-activate the plug-in
- Delete and re-install/re-activate the plugin
- De-activate all other plug-ins to determine if there was a conflict
- Re-write the shortcodes in case something changed
- Re-install WP
- Changed the active theme to twentyfifteen
But the problem persists. I have another site, hosted on the same server, running the same theme, and also running WP 4.3.1 but still using LCP 0.62. The plug-in works great on this site.
Any suggestions are appreciated.
