@croco2511,
I figured this out. This is the loophole to GoDaddy’s system:
- Download the entire folder wp-includes to your local machine
- Make the edit to category-template.php on your local machine (you should be able to edit the permissions locally
- Via FTP, rename wp-includes on your server to something else (i.e. wp-includes-old)
- Upload your local copy of wp-includes to your server
- Flush the GoDaddy Cache
- Enjoy your website sans error
This worked perfectly for me.
