I moderate a Union Message Board built with Simple Machines Forum. In the past, I've been able to upload attachments. This feature stopped working recently. When I try to upload an attachment, I get an error message. When I try to view an older attachment, I get a 404 not found message. This started about three months ago. Has this happened to anyone else? Is there anything I can do to fix it?
Thanks and kind regards,
You "get an error message"? What, specifically, is the error message?
What is the URL of the site (specifically, please, a forum post with an "older" attachment)
