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.
