Articles are not saved in OJS


Current version OJS:
PHP version: 7.3.19-1~deb10u1
Apache version: Apache/2.4.38 (Debian)

Have you encountered a problem in OJS. The fact is that in OJS itself I try to send an article, submitting an article consists of 5 stages, but after pressing the save and continue button, it does not go to the second stage, it just starts an endless download (the download circle is spinning). I checked it on the local Open Server, everything works there, but on the server of the institute there is an endless load.

I looked at the error log, but there is no error related to this problem, however, using the browser I debugged and gives an error after clicking save (“DB Error: Field ‘author_id’ doesn’t have a default value”). I went to the phpmyadmin of our site, and I didn’t quite understand what the problem was, since everything seems to be correctly spelled out in terms of sql regarding ‘author_id’ (screenshots below). In this case, this error began to belong to error 200, previously belonged to error 500.

Or is it just a statement by the browser and the error may be in a completely different place? All the same, I think that the database has nothing to do with it. Also, everything works on the local server, but the online server does not work.
