1. The problem
Error: “JSON API Error pages is not iterable” when posting to WP
So I went through the article … and I noticed that the spintax is not being processed after the article creator is done. See here:
{<img class='aligncenter' style='display: block;margin-left:auto;margin-right:auto;' width="{600|601|602|603|604|605|606|607|608|609}px" alt="Is french dressing healthy"
As you can see, there is still unprocessed spintax. So my first guess was that JSON was erroring out due to the extra sets of curly brackets.
So I removed all of them and structured the HTML correctly. However, even after fixing the HTML … the same JSON error still happened again.
