Warning when adding task

[Synchro]

When I click the 'new task' button, the new task form appears, and above it is this error:

Warning: Attempt to assign property of non-object in /var/www/html/dotproject/modules/projects/projects.class.php on line 67

That line is:

$obj->project_percent_complete = db_loadResult($sql);

So it looks like $obj is not an object at this point, which must mean that the earlier call to parent::load($oid, $strip) is not working.

The task does get added.

I'm running PHP 5.0.4 and MySQL 4.1.10.

Actually, this error pops up all over the place, sometimes several times on a page.

The problem could be that PHP 5 is not supported
