All articles disappeared after OJS upgrade

After upgrade from OJS 2.4.8-3 to 3.1.1-2 all articles completely disappeared from the site. The issues remained, but no trace of articles. The URLs where articles used to be now return 404 error. Tried with different versions of PHP - no effect. Tried to upgrade to 3.0.0 - the same thing happened.

Hi @Igor_Kupriyanov

What is missing are articles or their PDF files?

Have you check your PHP error and webserver log? A 404 error often is record on these files.

I also have problem that a few of my pdf has missing after upgrade from 2.4.81 to ojs 3.2.1-2. from 7 articles, about 6 file pdf missing.

Is there any step to recover this file without using upload again from galley? Because if I do that, it will show the revision file.

Ojs 3.2.1-1

PHP 7.3
MySql 5
