Wow, as usually, it was a simple thing.
Works fine even on Internet Explorer.
I did exactly what you told me: I installed WordPress and I downloaded the theme again. I did not get any errors during installation, neither the WordPress nor the theme but still I get the notice
Undefined variable: sliderHtml in /hsphere/local/home/ciq2012/ciq.org.mx/comunidad1/wp-content/themes/incarnation/includes/helper-template-dynamic.php on line 1054
At this time the theme does not work on Internet Explorer, I only get a blue screen.
I hope you can help me.
