Editor's mail with no reviewer's comment Recently I submitted second revision of my manuscript in a highly reputed mathematics journal. My first revision was a major revision while the second one was a minor (with some terms like paper is ready to be published). After submitting my second revision I got an email from the editorial board which asked for further revisions of my manuscript. But, what is troubling me is that there were not reviewer comments in the mail. Also there were no attached files with reviewers comments.

Edit: I took only three days to resubmit my second minor revision and after another five days I got this mail with  no reviewers comment.
Also, there is only one reviewer for this manuscript.

Edit: At the end of the mail that I received it is written that "Reviewer's comment"  but it is showing blank. Submission status is "submission needing revision" (Revise). But I am not able to find the reviewers comments.

I am worried. How come this is possible?
Instead of trying to second-guess what might have happened you should simply contact the editors and ask what revisions they wish to see you perform. The reasons for the lack of information could be any of the suggestions given but could also be a mistake, an attachment that was not passed on or a mail sent by one person who has not seen your recently provided update, the list of possibilities is long.

So, e-mail the editor or journal and briefly explain what you received and how the lack of information makes revisions impossible.
