We are not able, after migratio, to insert new attachments and download old ones.

Here some further info:

• we did a warm-up in test environment ad all worked well;
• old and new version fields in file are identicaL (ie: the ID of the attached file);
• between test and production environment there are no differences in property files;
• the generated url to download the attached file is ok (as old one version ), and file IDs in URL match to the ones in the DBs (old and new)..

Are there any other propery to set more than those ones in config_inc.php ?
