Function: multi-level navigation. / Plugin for version 2!

[Jeff]

[Update: see comment 79, below]

New dev environment hiccup now that I'm using a live server.

I get a blank screen when attempting to save a modified page. The site health check is clean, aside from the version status, line 51 of health-check.php:

Code:

$verstatus = $apikey->status;

The multi-level menu's mentioned in two error messages:

Code:

Warning: Cannot modify header information - headers already sent by (output started at /home3/grassygn/public_html/getsimple/admin/plugins/zegnat-multilevelmenu.php:1) in /home3/grassygn/public_html/getsimple/admin/changedata.php on line 166

Line 166:

Code:

// redirect user back to edit page
header("Location: edit.php?uri=". $url ."&upd=edit-success&type=edit");

And the second error message:

Code:

Warning: Cannot modify header information - headers already sent by (output started at /home3/grassygn/public_html/getsimple/admin/plugins/zegnat-multilevelmenu.php:1) in /home3/grassygn/public_html/getsimple/admin/inc/cookie_functions.php on line 24

Line 24:

Code:

setcookie($saltCOOKIE, sha1($saltUSR), time() + $cookie_time);

I'm stuck. Any help would be awesome.
