I have the same problem described here: Can not open a specific plot
I can view this plot: https://plot.ly/~caseguide/7?share_key=5W2d1WOfhPPq0iyHmuTqlx
But I cannot edit it. When I do I get the following error: parseSrcTag: no valid uids to retrieve
I didnt see a solution on the other thread, although multiple people have reported it.
