I just installed pihole and it was working perfect. I then installed open medial vault and it is coming back with
"FTL failed to start due to failed to create listening socket for port 53: Address already in use"
also error
"There was a problem applying your settings.
Debugging information:
PHP error (2): fsockopen(): unable to connect to 127.0.0.1:4711 (Connection refused) in /var/www/html/admin/scripts/pi-hole/php/FTL.php:47"
I've looked up all I can to fix this but I'm very green with linux and systems. I really just copy and paste most commands to set up things on my RBP. I wish I knew more how to config/setup/understand all the behind the scenes stuff but it's more than overwhelming to try and learn 
Thanks in advance. Sorry for the word/copy-paste soup
wouldn't let me upload my debug log ("Error message: curl: (6) Could not resolve host: tricorder.pi-hole.net [✗] There was an error uploading your debug log.", this is the best I've got:
