If you are seeing this message, upgrade your plugin and use the new “Remove gallery” option from the excerpt menu. That should solve the problem.
You might also need to access the Cincopa options page by logging into your Wordpress Dashboard and changing the excerpt handing by simply trying each one of the options until you get the right results.
If either of these don't do the trick then it means that the theme developer didn’t follow the excerpt guidelines (post template should use the the_excerpt() template tag) when developing the theme. You can the following:
- Contact the theme developer and ask them to update the theme.
- Manually set the excerpt for each of the posts - do this by editing each post and set the excerpt text (below the main text box).
- Changing your theme
