Hello to all !
I recently upgraded from 3.9.3 to 7.0.4. Following the installer i successfully upgraded the database to the version current schema and the whole process finished with no errors.
After the update every time i create an order/invoice/etc i get the following error: Error Duplicate entry ‘facture/ΠΑΡ999-121_invoice-1’ for key ‘uk_ecm_files’
If i delete the the records from the table uk_ecm_files the error stops but later on on other invoices or if i upload a file the error appears again …
How can i fix this ?
