So recently whenever I add the shortcode to a page it wont let me update that page and the page wont work. I uninstalled the premium version and when I install the free version the free version will work. I really enjoyed this pluggin since I upgrade. Very upset it stopped working.
I can see you also displaying post grid inside post content that's make the cause,
Here i have created a dummy post grid that works fine, (that exclude post grid inside content)
How many post you displaying post grid inside content? i guess the issue happening together siteorigin page builder.
