Attempting to launch my first conrete5 site from local to online, running into a lot of issues though.

I'm getting this error
file_put_contents(/var/www/html/CandyMountainMusicv2/application/config/generated_overrides/concrete.php): failed to open stream: Permission denied

I've been following along with this guide (https://documentation.concrete5.org/developers/installation/moving-a... ), and I've seen a few other things but I'm not getting very far. Currently, I can reach my login screen, but after typing in my credentials I get the error above.

My index page and my subdirectories are all blank when I navigate to them, but I believe they exist. (edit: turns out this part was just a git mistake).


I am using Digital Ocean on an apache server.

I'm hoping someone out there has a bit more experience with this than me.
