Permission denied!

When i try to save i file, i’m having an error.

Can you create a new file in that folder?

yes i can, but i want to save the changes in that folder.

One step at a time. Since you can’t save that file, but you can create new ones, there might be a permission issue with that file. You could look at the permissions, or you could just try to delete the file using your file explorer or the terminal, then make a new file with the exact same name and contents.

can you help me with this?

What do you need help with?
