This occured a few weeks ago, and I have yet to figure out what is wrong.
No new or previous files uploaded with the advanced attachement plugin works anymore.
They get uploaded, but are corrupt / not embeddable. Images will not be viewed in either the post or in the "Forum Attachment" wp-admin page, and i.e. zip files that are uploaded (or previuosly uploaded) will not unpack. It seems like all files are corrupt in some way.
When disabling and uploading natively, everything works, and images uploaded without plugin becomes embedded when activating it.
Tried to delete and re-activate.
Plugin v. 2.1.2. Wordpress 5.9.3
See attached images. Any suggestions?
