Form Uploads
We are aware of the problems with the form uploads and are working with Gravity Forms on a solution.
EDIT: It appears DISQUS was causing some timeout issues with the submission forms. I’ve reset DISQUS and test submissions have uploaded correctly. Please let me know if you run into any additional problems. I apologize for the inconvenience.
EDIT 2: 524 errors are back even after turning DISQUS off. Back to the drawing board in figuring this out.
EDIT 3: I am cautiously optimistic that SmushIt was causing the timeout errors. I discovered when I tried to publish something I would get a Smushit error about the same time as the 524 error. I turned it off and so far all submissions have gone through.
