I couldn’t reproduce the issue using latest versions of it and using publicize module.
The Jetpack plugin has a newer version 3.7 so could you please try using it?
This can be due to other plugin conflict on your site so please try temporary deactivating all plugins except jetpack and see whether everything works fine.
Can you please try temporary enabling WP_DEBUG mode? To do this, just go to wp-config.php include this:
define('WP_DEBUG',true);
You might already have a line for WP_DEBUG, so just make sure it’s set to true.
Let me know what errors if any you are getting when you face this issue.
I have tested again but couldn’t reproduce the issue with Travelify theme.
If you could troubleshoot the issue as described in my following reply posted previously then we could reproduce the issue and would definitely help you to resolve the issue.
