Fatal Error on Selection of Backgrounds page

Hello!

I'm in the process of building a website. I am using a theme that supports woocommerce. After installing the HPWallart plugin and selecting what kind of product I want, it comes up with this error message:

Fatal error: Call to a member function getCategories1() on a non-object in /home/vp811/public_html/modernmural_newtheme/wp-content/plugins/hpwallart/includes/scenes_fotolia.inc.php

I do not have a fotolia account or any of the other accounts that it asks for. I want customers to either select from our WordPress media file or to be able to upload their own.

Here is the link to the page (Nothing is really completed):

Please let me know what steps to take.

Thank you!

Dear VP811,

this error happends if you have a bad configuration in the Fotolia API.

Please make sure yo have the propper configuration for this API using the next information.
