I’ve looked and looked but I’m completely stuck…how do you upload a file to a topic post? I can see the icon to upload an image, but what about documents? Help! TIA

For security reasons, attachments/documents are not allowed by default.
You have to **whitelist** the extensions using the “`authorized extensions`” site setting.
