My entire DP 2.0.1 seems to be working fine, with all modules. But the files module does not display any checkin/checkout icon or a link. When I upload a new file, there is no place where I can check in a file. Similarly when I click on the edit file icon, I am taken to the page where I can modify the properties or upload a different file or download the current file with no restrictions.

Shouldn't there be a restriction on changing the existing files?

There are two related configuration options to make these two things work accordingly.

Could you please let me know what configuration options? I have checked the system configuration page, but it doesn't indicate anything. There is only one option that relates to CI. Checking/ unchecking this doesn't help. :(

Preserve File Settings on CI - on
Allow Editing of Previous Versions - off

Thanks,

I tried the settings. The icons still do not appear. :(

Perhaps the icons are broken. Can you check the actual images?
