Are you sure you are importing it correctly? Are you going to Products & Plugins > Manage Products > Add/Import Product?

Yes, I am importing correctly. I discovered the problem was that I was double gzip encoding the content. I had gzip enabled in php-fpm and nginx. When I disabled it in php-fpm the content encoding error went away and I can install all products without problem. I'm not sure why I didn't get a content encoding error with all content when I had it double encoded, but at least it is working now.

Thanks for posting your findings. :)

Even know you have fixed the problem but the link I gave you was the right place

I disagree, this had nothing to do with that product, and I made a point to mention that in my second post. However, I believe this thread is solved so there is no need to argue about that point. :)

You had a problem with the Shoutbox from dbtech I don't see how you say it does not belong in that plugin topic even Lynne told you twice to post in the correct section ie the link that I posted

Either way, issue has been resolved, I see no further need for discussion on the topic. :)
