You’ve been already sent updated file import.php to fix the issue with demo data installation. Please check your email address.
To fix slider issue, go to Revolution Slider > open slider settings > click “SlideShow-Auto” and save the settings.
I’ve just installed demo data for you. Please check the site.
Currently slider can’t be viewed because you have mod_security disabled on a server. When I try to preview slider in Revolution Slider settings I get this error:
“An appropriate representation of the requested resource could not be found on this server. This error was generated by Mod_Security.”
You need contact your hosting provider concerning this issue.
