Once I install the compoment and the plugins, i get a blank white page which returns this error:
Warning: require(/Applications/MAMP/htdocs/knowflair/administrator/components/com_virtuemart/helpers/config.php): failed to open stream: No such file or directory in /Applications/MAMP/htdocs/knowflair/plugins/system/vmuikit_onepage/vmuikit_onepage.php on line 51
May be problem in your Virtuemart installation. First Rename our components and plugins files. then install virtuemart again. after that reinstall our component.
if any problem add your site admin and ftp details we will take look on this.
