The Sitecore registry contains useful information about the user. For example, the different checkboxes that needs to be checked or unchecked in the ribbon is managed by the registry. This allows to gain in performance.
Today, I’ve helped a user on Stack Overflow to fix the following error on Sitecore 8.1:
“The maximum amount of data that you can upload is NaN undefined”.
So, I have decided to blog about this issue and how to fix it.
