After two months the status of the manuscript under review changed from review in progres to ready for review. I dont understand is my paper yet to be reviewed? Dont know the workflow of River Valley Review.
Just a guess, but a reviewer may have backed out so they are back to square 1. Probably no reflection on the paper. It may also been that the editor wasn't satisfied with the review he/she got so started over. Reviewers get busy just like authors.
Another possibility is that the editor got back inconsistent reviews.
Be advised that dealing with publishers can be very frustrating. Not the finest aspect of the academic life.
