Uploading a logo or cover image fails with "Failed to upload image"

What you are seeing

You pick a logo or cover image for your site and get the message "Failed to upload image".


#Why it happens

Capable Sites keeps your logos and cover images as attachments in a dedicated Confluence space, with the key CAPABLEASSETSTORE. If that space is missing, or the app can't reach it, the image has nowhere to go and the upload fails.


#What to do

  1. In Confluence, check that the CAPABLEASSETSTORE space exists.

  2. Make sure the app can reach it.

  3. Pick your image again.

The file uploads the moment you pick it, before you press Save, so you'll see straight away whether it worked.



Found it? Good.
