All fields using the FF Matrix fieldtype (version 1.3.5) have suddently stopped working. My client can no longer upload files, and the fields can no longer be expanded to add new rows.
This is an old but very active site using EE 1.6.8 build 20100121. The FF Matrix fields are the heart of the site, and my client reports that they were working fine until yesterday.
Is this a known issue? Is there an update to FF Matrix that is compatible with EE 1.6.8 which could fix the problem? Or some other fix?
