Via github I installed the 2.0.3.2. RC version on my digital ocean VPS. All seemed to work fine, but just like many others i got problems with the JSON syntax error. I spent hours reading through forum pages about
All of these solutions didn't seem to work... When i finally found out that I had my VPS access restricted on IP address and removed this restriction the order history update seemed to work fine so I assumed ALL was ok.
Today when I tried to edit an order, the same following error came popping up. So I started going over the forums again for a solution.
While heavily frustrated trying things i bumped in to this strange behaviour. When on the first page of order editing I get the error, but when I select the standard shop... all works fine... I can edit the order exactly how i want... but when i switch the option back to the store the order was placed in... it responds directly with the same error (see attachment).
I'm not sure if there are any other multistore users that are on 2.0.3+ that have shops that are working fine?
Could you think with me? Could it be something with the Cross-Origin Resource Sharing policy? All suggestions are welcome!
Go to Settings, edit your store (not Default), and on first tab (Genaral), make sure that your SSL URL is set.
If you don't have SSL, then set the same value as Store URL.
Hope this helps.
