Thanks Arvish,

But I already had try your solution, and it doesn’t work, I get the same error message. I have downloaded the latest 3.02 version off enfold from themeforest.com and try to upload and install true ftp, but it don’t work.

Do you have another solution?

Sorry,

I mean can I switch header.php with content or layerslider in the theme custom code or in wordpress custom code?

And wich lines do I have to change?
