My attachments suddenly went missing after a recent update and to troubleshoot I need to know what the schema is for how files are stored in the file system. The plugin is configured to save files in a specific folder in the root. One example link is:
/file.php?key=ljjogjx4fgkb4t072fdtauqhyca9q9za&expires=1606780800&signature=5755957d494d227409efd563a85b8a5a318ec461&disposition=inline&id=158
When I look in the file table I see the corresponding entry.
When I look in the directory specified in the plugin settings for uploads, there are a bunch of empty folders in there. I've searched for any file using the key value as the name and nothing is found.
So the plugin should save the attachments in a specific folder, which only contains a bunch of empty folders, and the file_chunk table is empty. Where are the attachments stored and what are they named, if not the original file names?
