Error trying to update my Payment Plugin on the Marketplace

Hi,

I have developed a Payment Plugin for Netcash South Africa. The current version of the plugin on the Marketplace that is approved supports nopCommerce versions 3.90 and 4.20.

I have added support for nopCommerce version 4.30. I ticked the "4.30" checkbox (3.90 and 4.20 already checked), selected my new ZIP file package (Netcash.zip - same as current file), but when I Edit my Extension, and attempt to upload the new package I just the following error:

"Error on uploading: An error occurred while uploading the file"

Should I not Edit my existing extension? Should I rather create a new extension? Or am I doing something else wrong?

Would appreciate any assistance.

I am getting the same error. The size of the .zip file is under the limit. Can not imagine what could be the problem.

We're looking for this plugin for Netcash. Have you been able to resolve this upload issue yet?
