When i open and edit the .json file for the gui shop it all goes well then i go and upload it to replace the old one and i restart the server and it will never save the new file i upload. I have been trying to fix this all day but nothing seems to work 

You MUST use https://jsonlint.com/
GUISHOP will rewrite the config if there is one error. Like a comma at the last line between {}, or the lack of one after ] or } when there needs to be one.
So validate, or your up to 4500 iline guishop.json will be over written.

I do it every time I change anything.

Thank you so much I just did this and I literally forgot 1 single comma.
