Forum 4.0.6 Error uploading images (ATTACH= CONFIG)1948(/ATTACH)
 

Hello, since 4.0.6 version a user of my forum is getting problems uploading images to a forum.

They obtain this error when trying to upload them:

(ATTACH= CONFIG)1948(/ATTACH)(ATTACH=CONFIG)1947(/ATTACH)(ATTACH= CONFIG)1946(ATTACH)

How can I solve this?
