Multisite activation page header shows as "Page Not Found"

[nullvariable]

When activating a new user the header for wp-activate.php renders the title as "Page Not Found" and returns a status code of 404.

This appears to be the case with an activation key or without.

The attached patch modifies the file to unset the 404 status and apply a generic title to all versions of the page.

this fix could mirror the current fix applied to ​wp-signup.php found on line 35.

I added a filter to the wp_title function that outputs a more descriptive generic title but this could go either way.

If this fix seems to be the best way to approach it currently, it may be worth going back to wp-signup.php and adjusting it to follow a similar pattern.

fixes 404 status and outputs a generic header (removed debug line)

I can confirm the 'Page not found' title in trunk on wp-activate.php. The header is also a 404.

I haven't tested the patch yet or investigated the underlying issue, but it appears to do too much at first glance by adding a filter/function for the title.

404 fix only

I've uploaded a patch that only resolves the 404 issue.

I thought we had fixed this, see #13638.

wp-signup.php still has $wp_query->is_404 = false;

I can't reproduce this on trunk with any Twenty* theme.

You are correct. wp-signup.php still contains this code.

The file at issue here is wp-activate.php, this ticket is about applying the same fix to wp-activate.php as was applied to wp-signup.php.
