OJS 3.3.0-21: API error

Software Support
1

I updated my OJS version from 3.2.1.4 to 3.3.0.21 and encountered a problem that I initially thought was a database issue, but checking the database confirmed the data is fine.

Then I analyzed the PHP logs and saw that the frontend is calling a method in the API and returning a 500 error because the method doesn’t exist in the SubmissionFileDAO class. The method name is “lastSubmission” or “lastRevision”, something similar.

Because of this error, I’m unable to access/view the files submitted by authors to my journal.

Is this a version error?

Could someone help me with this?

Hi @Kelvin,

Can you find and quote the exact error message?

Hi @Kelvin,

The actual error message should appear in the line just above what you’ve quoted. (The #0 to #6 lines are the stack trace, but what we need is just above that.) Can you include it?

Thanks,
