Can't add new products

[spruce]

I changed the model names under product types except for Product - Free Shippingshipping.
I can't add any items under the other option even after i put back the original names.
I can add items under the Product - Free Shipping
How do I fix this
or do I have to reinstall
Kindest regards

When you made your edits, you probably changed a CONSTANT or made some other error that php didn't like.

Go back to the files you edited - particularly the one that is appearing to cause the problem - and go over your edits to make sure you have not fouled up the php SYNTAX.

When you edit the code files, the following advice may be helpful.

1. Make a BACKUP of the file before you edit it. Create a special folder - either on your server or local drive - where you can store these backups during your edits.
2. FTP a copy to your hard drive, and edit it off your harde drive, using a PLAIN TEXT EDITOR. Notepad++ (not notepad... this one is NOTEPAD++) is a good plain text editor.
3. Save the edited copy on your hard drive.
4. FTP it to the server (if it is an override file, then it should go into your CUSTOM template override folders)
5. if your edits break the cart, restore the backup copy/copies.
6. Open the edited version on your hard drive and try to see where you have gone wrong.

You say... All I did was change the names...

HOW did you make these changes?

What did you do?

Give me a LOT of detail about the process you used to make these "changes".
