I am facing a “503 Service Unavailable” error when I want to upload the themes which are gifted for free this month by Envato also named as “Freebies”. At the same time and circumstances, I don’t have any problem while installing the theme I’ve purchased in the first place: “Kallyas”.
The problem occurs when I try to install the free themes such as: Kyoto, Rabbit, Sigma, Essential, Tokoo, Lordcros. It starts uploading the file, and crashes with the 503 error in the middle of the upload.
I am sure that I’m uploading the right .zip file. And there’s no problem with Kallyas, I have installed and am using it problem free.
It would be very helpful if someone could explain why I’m facing issues with the free ones.
