Problems to assign Reviewer "Failed Ajax request or invalid JSON returned"


I have a big problem, recently when I try to assign a reviewer, I constantly receive the error message “Failed Ajax request or invalid JSON returned.” if I try many times, sometimes I can get it to work. Can you help me fix this issue please??

The problem has evolved now I can’t even access the submissions or archives, any help please ???

Hi @iqfvp,

Are you asking about OJS, or OMP? What version are you using? (Please include this information in your posts.)

I got the same error message when assigning reviewer to manuscript in OJS 3.1.1.
