This is a continuation of this problem:
www.kunena.org/forum/k4-0-kunena-support...aded-attachment-file
The problem never went away but for a while I had it narrowed down to jpg, png and other image formats.
It persisted through the upgrade to Kunena 5 and the problem I describe below affects also Kunena 5.
Today I found this:
www.joomlart.com/forums/topic/unable-to-...les-on-kunena-forum/
Although the annswer in the forum is incorrect, the problem is not in Crypsis, Crypsisb3 works fine when the actual problem is solved.
The actual problem was that I hadn't defined max width and height for images in Kunena settings. I had set max filesize but not pixel limits. This prevented any kind of attachments from being uploaded and attached to messages. Now that that is fixed attachments work.
I rather think there SHOULD be a warning in the settings that if you do not set those pixel limits to width and height you can't attach files to messages.
