Assistance Needed with PKP-PLN Plugin Issue - OJS 3.4

Hello,

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!

There are probably details in the php log.

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.

then you should definitely check the php log. you could also inspect the response in the browsers network inspector. Maybe there’s a hint.

Hi!

Can you please simulate the error again and share the latest entries from your error log?

Thank you very much for your advice.

Hello Jonas Raoni,

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?

Thank you for your assistance!

There’s no limit regarding the year, if some issues are missing, there’s something wrong and I can try to help to investigate :slight_smile:
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.
