Hello,
I upgraded my site to SEBLOD 3.6.0 and was curious how this new feature (of deleting all files with content) works. Well, it didn't.
So I installed whole new empty instance of Joomla (3.4.1), installed SEBLOD, added to built-in 'Article' form field 'upload image', then created an article with an image, then moved it to trash, then emptied trash, and... the uploaded pics are still there in the subfolders with article id. I created another articles, trying to change the storage of 'upload image' plugin back and forth - still no success.
Am I missing something? Is there a switch like 'enable deleting attachments with content' in options that I can't see?
