I am submitting articles through DOAJ plugin in OJS. Some article were registered successfully while some giving below error:
Deposit was not successful! The DOAJ API returned an error: ‘1 - {“status”: “forbidden”, “error”: “DOI or Fulltext URL have been changed. This operation is not permitted, please contact an administrator for help. (ref: 03e3818b-419f-11ee-aeaa-47a42d843b88)”}’.
I have compared both successful and error articles, but couldn’t find difference.
OJS Version is 3.2.1.2
Kindly help me to resolve this error.
