Sorry, there has been an error.
This does not appear to be a WXR file, missing/invalid WXR version number
We do not have WXR files on our theme so it could be a plugin issue.
Please, disable your plugins except the ones required for that pre-built website, and check if the problem persists.
Moreover, I also suggest contacting your hosting provider, to check if it is not your server problem.
I have contacted the host and there is no problem on his part.
However, I tried the template on another server and I'm still facing the same problem.
This is the list of plugins https://www.awesomescreenshot.com/image/27405365?key=726294012613c8446f824b25825b55b8
Does it happen with only this demo or all of them?
Please send us the WordPress dashboard and FTP access privately thru the contact form, which is on the right side at http://themeforest.net/user/muffingroup#contact and we will check what might be the reason.
Please attach a link to this forum discussion.
It happens to all the demos.
I sent the admin and FTP information.
