I’m not sure what the issue is, I did a test on another site and the zip file uploaded just fine, I have not yet updated that WordPress, it is still running 4.3.4. On the site I had intended for this theme it keeps saying there was a problem uploading and to try again, it is running WordPress 4.5.2, is that an issue?
I have included the website info. I did not set-up the environment, and am wondering if that is the issue.
Thanks,
