I had a similar issue with trying to modify a portal entry that had changed.
@mattfullerton and @schlos are the main maintainers of dataportals.org. I am in the process of being made an editor.
For the moment, please provide the details here and we'll fix it.
We're looking for volunteers who may be able to improve the code so these changes can be requested more easily online.
Thanks so much for pointing out the change.
