my forum works with "approval", so I have to accept every applicant.
Sadly its not working. I can decline applicants, thats no problem, but the "accept" button just refreshes the applicants page.
what is the total number of applicants you have?
are you using the checkbox for approving all?
if you have a large number of applicants try approving one applicant at a time, and see if it works singly.
if you can approve singly, and can't approve en masse, it means the js is getting overloaded due too to many applicants for the process to handle.
I may not provide the completed solution you might desire, but I do try to provide honest suggestions to help you solve your issue.
