Warning: file_exists error on Appearance page

[alpinenut]

Hi,

Just installed Prestashop and all looks fine. However, went to look into changing the logo on the Appearance page and noticed the following at the top of the page (Note: the same error appeared twice):

Warning: file_exists() [function.file-exists]: open_basedir restriction in effect. File(/customers/suffolkwalkingsticks.co.uk/suffolkwalkingsticks.co.uk/httpd.www/themes//debug.tpl/preview.jpg) is not within the allowed path(s): (/customers/suffolkwalkingsticks.co.uk/suffolkwalkingsticks.co.uk:/var/www/diagnostics:/usr/share/php) in /customers/suffolkwalkingsticks.co.uk/suffolkwalkingsticks.co.uk/httpd.www/swsshopadmin/tabs/AdminAppearance.php on line 54

Could anyone please advise what the above means and how I can resolve it?

Thanks.
