Can't update this collection upon slight edit of photo

Made a few edits to some photos in an album.
Can’t Update error: An internal error has occurred: JSON.lua:197: html passed to JSON:decode():

500 Internal Server Error

500 Internal Server Error


nginx

I can update other albums with edits. Any thoughts?
Thanks,
Ji

I deleted the album and started over. It works now. But I don’t understand the error message. Thanks.

Hi @coyotepixel, it means something failed on your server. 500 errors are generic and don’t provide any information about what might have happened. If you have access to your server error or php logs then they could shed some light on it.
