Thanks Zubaz. I am editing an existing skin. When I click the edit link on the skin page, it loads 4 fields (skin name, category, description and tags) that were already associated with the skin.
I do not need to upload the skin or preview. There is no change. I just want to update the description. So, I changed the description and clicked the submit button.
The link was originally upload2.aspx. Today I tried upload.aspx as well. The error is same.
