Fatal error: Cannot redeclare class order

On the first page of my checkout, I'm getting the following error

Fatal error: Cannot redeclare class order in /homepages/11/d210728506/htdocs/includes/classes/order.php on line **20

**I'm also having another issue where the only checkout module I can get to work is a freeshipper module. All the other one's don't work at all. Could the two issues be related?

part of my order.php is below, line 20 is bold

a quote by DrByte.

"cannot redeclare class" means that somewhere in your program code that class is being loaded twice.
You'll have to hunt down where it's loaded and stop it from loading a second time.
Perhaps you have duplicate or backup copies of files that are getting automatically loaded ?

have you renamed any core file ? have backed up any file that is still on your sever ? zencart autoloads many files , if you have renamed a file that still contains .php extension ,might be loading as well causing this error.

Do a search in the Tools ... Developers Tool Kit ... in the bottom input box on:
class order

See what files are using it ... there can be only one, as indicated ...

You may have a backup or a renamed file or a misplaced file in one of the auto loading directories causing this ...

The Developers Tool Kit is your friend ... and will help you locate the problem ... :smile:

This is the result the developers toolkit gave me, as far as I can see, class order is used twice, one is in the admin. Should those two be affecting each other? the result I got is

Thanks for the help so far.

I must also say that I had a stock by attributes plugin installed a while ago and I have the ultimate SEO urls plugin installed, I also had the one page checkout installed and I told the programmer to disable that and he did. I don't know if its remnants of those that are giving the problems.

You show:
Searching 48 files

Make sure that you are using the bottom input box, you should see 900+ files being searched ...

This is what I got from the bottom input box

Searching 1440 files ... for: class order

Well ... this rules out two files with the same class ... :smile:

But now it is harder in that "some file or files" is calling the order twice ... and that is much harder to find ... :blink:

One thing you might try, for an obvious double call, is try a search on:
require(DIR_WS_CLASSES . 'order.php');

This comes up with 11 calls from various files ...

What version of Zen Cart?

Do you have any add ons?

On the off chance it is something with a template and override, what happens if you switch to Classic Template?
