Error when selecting Shipping Methods

[WebAlterations]

When i click on Shipping Methods in the admin panel, I get the following:

Fatal error: Call to a member function getCode() on a non-object in /home/mywebsite/public_html/app/code/core/Mage/Usa/Model/Shipping/Carrier/Dhl/Source/Shipmenttype.php on line 34

this just started happening without changing anything in the site..

any thoughts ?

Are you using the Magento compiler?

[WebAlterations]

It was run once, but then turned off while we were still developing the site.    i was waiting to turn it back on until the site design is 100%

Compiler Status	Disabled
Compilation State	Compiled
Collected Files Count	7432
Compiled Scopes Count	4
Scopes Compilation Settings	default

Can you run the shell command (into your Magento root directory)

php shell/compiler.php clear

After that you'll see this message: "Compilation successfully cleared".

Then check again the compiler status and you'll see these lines:

Compiler Status:          Disabled
Compilation State:        Not Compiled
Collected Files Count:    0
Compiled Scopes Count:    0

Right now your compiler is fullt disabled.

According with your first post, you compiler is disabled but the code is compiled. You need to delete de compiled code.

[~/public_html]# php -f shell/compiler.php -- disable
Compiler include path disabled

 [~/public_html]# php -f shell/compiler.php -- clear
Compilation successfully cleared

[~/public_html]# php -f shell/compiler.php -- state
Compiler Status: Disabled
Compilation State: Not Compiled
Collected Files Count: 0
Compiled Scopes Count: 0

still getting the error

i found that the config_core_data is missing all of the carrier information.

looking at a working site, i looked at the SQL database for the Magento database.

i did a search for "shipment_type" and found the following:
1 match in core_config_data
1 match in eav_attribute
222 matches in sales_flat_order_item 
Total: 224 matches

but when i did a search in the site that is erroring:

1 match in eav_attribute
2 matches in sales_flat_order_item

so it's obviously with the core data
