trouble uploading copies of files

[hanbar]

Help!

 

To correct an error that I created in a couple of files, I uploaded original copies of the files from my computer to my host account. I put the correct files in the correct folders. When I tested my website, I got the following message for the pages controlled by the files:

 

The script /usr/local/psa/home/vhosts/anbeadsjewelry.com/httpdocs/shop/product_info.php cannot be world writable.

 

Does anyone know how to fix the problem, or what this message means? How can I avoid the problem in the future?

 

Thanks a lot,

Hannah
