Sakin, thank you for replying to my question.
I think you misunderstood my question. The “Older Posts” is present in the “Live Preview” for Simple Catch Pro on this very website (http://catchthemes.com/demo/simplecatch-pro/).
If I understand correctly, you are saying that both Simple Catch and Simple Catch Pro use “Previous” and “Next” and that the “Older Posts” button on the demo is incorrect.
Thank you for your assistance.
