I’m encountering an issue with the PKP-PLN plugin that I’m unable to resolve. When I try to configure the settings, I receive the error message: “Failed Ajax request or invalid JSON returned.”
For reference, I am using Open Journal Systems (OJS) version 3.4.0.3, along with PKP|PN version 3.0.0-1 compatible with OJS 3.4.
Any guidance on how to address this issue would be greatly appreciated. Thank you!
A thing that had me in the past (and that you could try) was the database migration didn’t perform when I first installed it. Disabling the plugin and then reenabling did the trick.
Thank you for your valuable advice. I’ve attempted to follow your suggestions, but unfortunately, I’m still encountering issues. I also tried deleting and re-uploading the plugin, but that didn’t resolve the problem either.
I’ve resolved the error, but it appears that I can only deposit papers up until 2021. Could you please guide me on how to deposit papers from 2022 to the present?
There’s no limit regarding the year, if some issues are missing, there’s something wrong and I can try to help to investigate
FYI we’ve got deposits coming from the URL (https://tapchi:8890/index.php/tckhdhdl), and we’re not able to download deposits from local URLs. If this is a test installation, you should ensure the automated tasks and email delivery is disabled to avoid such issues.
