Turn off PHP debug in Preferences - General Settings. They are notices and will cause no harm. Turn off the above and they will not be shown.

Here's an explanation from PHP Documentation that shows what is going on.

My provider seems to have just upgraded to PHP 4.4.1 and my test site, which runs with debug turned on, now sports a flood of these "Warnings". Is there any hope we can get some of this cleaned up soon so that the real errors and warnings are visible again?

- Thanks
