Hi Laura,
the plugin only works with a more tag. But it can only work, if the theme is using a correct query of the posts. Could you send me the category.php file from the (child-)theme, so I can have a look on it?
Thanks for getting back to me so quickly! It works perfectly with other themes. I should have known better because Genesis uses different formats. Thanks for developing this plugin!
I am glad to hear it’s not a general issue. I don’t own a Genesis Theme to test it. Maybe I can ask someone from my local community for a test drive in it.
But I will definitely write some more documentation and explain the requirements for the plugin to work.
