I’ve found a way, to sort by date….
In the database-tabel “ahm_files”, you start with the mysql command:
ALTER TABLE `ahm_files` CHANGE `description` `description` DATE NOT NULL
Then go ahead to your WordPress and go to File Manager > Manage.
Edit waht you want and write the date of the file into the field for the description, it’s the tall field.
Edit the php-file of the manager and write “order by description asc” or “order by description desc” in the specified lines(600 or 345).
Now it is sorted by date.
