Attached files not visible

From Dolibarr 6.0.3 I’ve noticed that are no attached files on my thired parties. They were created previos on Dolibarr v 5.x.x.
I’ve made upgrade to 6.0.4 … but still no files.
I’ve looked on data base and I’ve seen that all files are on table ecm_files.
I’m still on PHP 5.6, could be this the problem?
Many thanks in advance!

You can check your FTP if they exist. The files linked to 3rd parties should be in dolibarr/documents/societe but I don’t know why they don’t display in 3rd parties cards

Even if files are not into ecm_files, they should appears on tab attached files of thirdparty.
Table ecm_files contains optional additionnal data.

What happen if you upload a file after beeing into 6.0.4. Do you see it ?

Thank you for your time and your answerrs!
Not I can see clearly that I’ve moved files from one domain to another and most probably I lost them in copy process.
