Can't turn on heaters w/OctoPi

I can load .gcode files from the SD card and print fine but when I load from a computer browser and select Print, the bed and hotend heaters won't turn on. All else appear normal, the camera shows the image and I can see to layers.
Also, the autoconnect is selected but I still have to manually hit Connect.
Any suggestions?

Hi @petey!

Some more informations like they have been asked for in the template you have deleted would be quite helpful.

Thanks, I will repost information
