I can't quite figure out why data won't load into my store from a php file formatted in JSON.
I've verified the output of my PHP is valid JSON via JSONLint.com, but when I try to load the store I get, "Unable to load data using the supplied configuration.
Open in Browser:"
If I copy and paste the output of my php file into a file with the .json extension, everything loads fine.
Is .php not a valid extension for loading a store? I feel like I've seen examples where people have done it.
