Are you trying to submit on the install page or have you gotten past that point? Are you getting any error messages? Try to attach a screenshot or check the error log at /var/log/apache2/error.log and paste any errors you see.
I figured it out. I’n not sure what happened during the file copy to my www directory but I was missing some files. Once I got them copied over, everything fell into place quickly and I now have a fully functioning, mobile app enabled irrigation system! A BIG thanks to salbahra and ITDawg for the help.
