ok so im setting up my reef pi with a rasberry pi zero w. installed reef pi and got it running on the server but when i go to configure the ph probe im having issues. i set up the driver, extra ports, then connector on pin 0, and then when i go to the ph tab and set up the probe it gives me a 404 html error. not only that but then the ph tab will randomly disappear and i have to re check it and do the ole admin reload. has anyone else ran into something like this? ive been stuck for a while today. appreciate any help!
