Broken Webinterface, restore Default?

Hello everyone,

i tried my 433 MHz emitter with the wiringPi and messed up the default webinterface and, i believe so, the opportunity to control my OSMC with my android remote app because it cant connect anymore.

i followed this tutorial which is in german … the main points where i could messed up are these commands…

downloading files

sudo apt-get install apache2
sudo apt-get install php5

move the “special” webinterface of this addon
mv ~/raspberry-remote/webinterface/* /var/www/send443

changing the $target IP to my IP and changing some stuff for the house code…
cd /var/www/send443
nano config.php

can i restore the default anyway?
please help me … im running the latest stable release of OSMC.

sudo apt-get remove --purge apache2 php5
sudo rm -rf /var/www
sudo systemctl restart mediacenter
