Why don't my image attachments expand?

[External IS OPS]

When I click an image it just blips the screen and doesn't expand.

The f12 recorder says "

1. Request URL: http://wiki.sfmic.com/rest/files/1.0/files/content/8749156/byAttachmentIds
2. Request Method: POST
3. Status Code: 404"

Cause

This problem happens because one or more application modules accountable for rendering file previews has been disabled. The modules are related to below plugins:

• Confluence File Notifications
• Confluence Files

As Confluence restful calls used to render the files does not work without some modules made available through above plugins, the files are not rendered. To confirm that this is indeed the problem, you can grep the application logs for entries similar to the ones below:

2018-03-12 15:00:14,723 INFO [http-nio-443-exec-2] [atlassian.plugin.manager.DefaultPluginManager] broadcastPluginDisabling Disabling com.atlassian.confluence.plugins.confluence-file-notifications

2018-03-12 15:00:14,773 INFO [http-nio-443-exec-2] [atlassian.plugin.manager.DefaultPluginManager] broadcastPluginDisabling Disabling com.atlassian.confluence.plugins.confluence-files

And in parallel to that, you may want to capture a .HAR File and observe the response given by the application to restful calls - It should be a 404 since the plugins are disabled:
