Can you indicate the OJS version you are using please?
Please see our documentation here: DOI Troubleshooting
“The registration agency you use should provide you with regular error reports which describe broken DOIs.” - you should see if your registration agency (Crossref) can provide you with any error reports that indicate why the DOIs are not being registered.
Yes I contacted CrossRef. They said that the error is from OJS side so we cant do a thing.
The issue is since the DOI are not deposited so the cross ref guys cannot tell about broken DOI or any other thing. First task is that connection is not made. Should I provide you login pw for the OJS so you cant have a better look.
Thank you. I’m afraid we would need more information - did Crossref give you any indication of where the error was occurring on the OJS side? Please don’t provide us any login information - we do not do troubleshooting for users here on the forum who run our their own instances of our software.
