Unchecking a project's "Enable issue tracker" option doesn't do anything.

The fact you can still create issues is already reported (somewhat confusingly) over here: #524464: Issue node form still works for projects where issues are disabled

The fact the blocks don't honor the setting is a bug we should fix in project_issue. This isn't drupal.org specific at all.

Not that I know of. ;) There certainly haven't been any commits for this. So, if it's now working, it's some intermittent bug or something. Still needs investigation and a solution, IMHO.

Strange. ;) I certainly didn't see any patches go in that would have fixed this, and I'm sure it was broken. That said, I'm about to leave for 2 weeks and have no time to dig further. But, I'd be shocked if this was all working properly in all cases.

If you really wanted to be amazing, you'd write some simpletests to ensure everything works as expected. ;)

I can confirm that this has not been fixed. I assume it is a bug that peeps only on projects with specific attributes (created before X, has open issues etc.)

A local checkout and install of the project module showed me that in a clean environment, this is not reproducable. Which makes me even more suspicious of the problem lying in the specific drupal.org database.

This is certainly still a problem on drupal.org.

I can confirm this has been fixed on the Drupal 7 version of the module. Since Drupal 6 is not supported anymore, this should be considered fixed.

It only removes the link. It does not disable the project from being referenced in issues, see #524464: Issue node form still works for projects where issues are disabled

Yes, it removes the issue data shown in the project block.

This issue is reporting:

Since the other issue contained more details, I preferred close this issue as fixed (for the part that it has been fixed), and leave the other issue open. If it's preferable to close the other one as duplicate of this issue, it can be done so.

Oh I agree and left it closed because of that. Sorry that wasn't clear.
I just wanted to point that issue out to any followers of this one.
Which reminds me, we can use metadata for that!

I should have been clearer in my first comment. Reading it, somebody could think everything was fixed, while clearly it's not so.
I apologize for the incomplete, and partially true, comment.
