uploading a zip file

hi there I am trying to upload a zip file to my site (it is an icon pack) for use with the icon manager that exists within the thrive theme.

The file is just 13kb and my file upload limit is 1mb but I am getting this message

This file type is not allowed. Please try another.

The Thrive Theme support tell me I need to request that zip files are allowed by my host. What I don’t understand is do I do this via my website dashboard, my host control panel or somewhere else altogether.

I’m way out of my depth with this. Please help.

Thanks Sally
