Can't edit wp-config-sample

Hey there,

After trying to install a new theme my wp site became a blank page. So I tried to reinstall it. Through FileZilla, I deleted all the wordpress files and created a new database. However, I can’t edit the wp-config-sample file anymore. When I try FileZilla just seems to go round and round trying to do something but failing.

Here’s an example of the logs… I didnt know how much to paste here because its just going to continue going on forever.

Any advice? :/
Thankyou
