Addon File Structure Changed Since 4.3.1?

I had an addon for multi-vendor working thru version 4.3.1. it looks like our project is resuming, and I have installed 4.5.2, and need to install my addon, but I get invalid addon structure.

according to the developer doc, I think the zip is in the right format.

I looked thru the version changes since 4.3.1 but don't see anything obvious for the zip file format change.

can anyone give me a pointer?

thanks

Hello! You should check structure of files in your add-on. http://docs.cs-cart.com/4.5.x/developer_guide/addons/directories.html. Or can you show me your zip file in private message?

If the problem is not solved, PM me temporary FTP access or addon package. I will ask our specialists to examine it
