Hello community,
we have the same problem, see pictures/attachments below...
- ...but in principle for all Confluence page types (not just blogs),
- ...and not for all users either
- ...but apparently only with Microsoft Edge, because this worked for different users in Mozilla Firefox.
We therefore estimate that it may be an individual browser setting in Microsoft Edge that is causing the problem.
Unfortunately, we cannot identify and solve it ourselves with our “onboard resources” (experience/know-how).
Problem: pictures not shown on confluence page in read mode with microsoft edge.

Non Problem: ...but pictures are shown on confluence page in edit mode with microsoft edge.

Clearing the browser cache didn't help, the problem still persists.

Dear Community & Atlassian Support, please help us!
We can offer to look at the messages (errors) together (remotely) in the Microsoft Edge developer tool. Asking for an answer.
