OJS 3.2.1.2 Error with publication - cannot publish issue

We publish one issue per year. Last year everything was working fine, and now (after the latest upgrade) I get an error when I want to schedule for publication articles. I get the following error: “An unexpected error occurred. You may have been logged out. Please reload the page and try again”. However, if I reload I am still logged in, so no need to log in again.

PHP version is 7.2, so it is okay, all the details are inserted correctly. I would really appreciate if someone can help because we are stuck.

The eror log says (it’s just a part of it):

Hi @filipi,

I have the same error, can you tell me how you solved it

Most important thing is to have your server running on PHP 7.3 or higher. Update to the last version of OJS, and check your databases…
