Page not found error in pagination

@nishakumari: Be sure that your “Recipes” page and your “Single Recipe” posts do not share the same permalink. For example, if your recipe page slug is “recipes” and your single recipe post slug is also “recipes”, this will create a conflict.

You would need to change one of these. The easiest one is to change the single recipe permalink from the Recipes > Settings screen. Go to the Permalinks tab there and change the single recipe slug to “recipe”.
