Can't update customer's status?

Hi there,

I went in my admin a week or so ago and everything was fine. And now, I log in, I see the customer's name and how much they ordered on the home page of the admin, so I click their name. And then they don't show up. I search for their name and their old order shows up, but not their recent one.

What is going on?

Bump. Bump.

Do you have any admin debug .log files in your /cache folder? If so, they'll give you a hint as to what the problem is.

Hi, thank you for your response!

I do. I have about 1,000 files in there, but I just looked at the logs from July. There's one making reference to the orders.php on line 148, but I don't see orders.php in there. *By the way, I removed my full path to orders.php:

[20-Jul-2012 06:31:39] PHP Fatal error: Call to undefined function date_diff() in /orders.php on line 148

I have an orders_archive.php and orders_status.php. I looked in those files and nothing seemed to jump out on line 148.

Thoughts?

Search the forums for "undefined function date_diff". You'll see several threads which suggest you either have an outdated version of Zencart, or some mod files which are outdated.
