Help on document directories structure

Yes, I am sure!
And I have the same empty screen also when I click on Document in the menu tree...

I have found the Log files and I see into some ERRORS...
But I think it is better to send you the log files of the last 2 days, so you can see directly what has happened.
Furthermore, I can tell you that the browser console hasn't never shown some advice after my file operations, and that also the reset list presentation unfortunately had no effect (also because I didn't have never changed the column list for this kind of lists)...

The error is always the same:

But, obviously, I don't know what it means...

Hi,
using phpMyAdmin I have adjusted the tables "document", "documentversion" and "documentdirectory" of DB, and after various tests I have discovered that with version of ProjeQtOr 5.2.4 all functions very well and I see all the files and the full directory structure.

But when I try to upgrade to version 5.3.1, the problems recur (in the log file I read that there were "23 error during the upgrade to v5.3.1 version") and I can no longer see the documents and the directory tree of the archive.

Do you think that is a problem that can be solved or will I be forced to stay up to version 5.2.4 to avoid losing all my data and all customizations already made?
Thanks in advance
