Blank page at checkout: Permission denied accessing googlecheckout files

When customers go to checkout the screen is completely blank at checkout_payment.

In ADMIN > Modules > Payment I get the following errors

Warning: googlecheckout::require(/home/bodykits_net/public_html//googlecheckout/shipping_methods.php) [function.googlecheckout-require]: failed to open stream: Permission denied in /home/bodykits_net/public_html/includes/modules/payment/googlecheckout.php on line 44

Fatal error: googlecheckout::require() [function.require]: Failed opening required '/home/bodykits_net/public_html//googlecheckout/shipping_methods.php' (include_path='.:/usr/share/pear:/usr/share/php') in /home/bodykits_net/public_html/includes/modules/payment/googlecheckout.php on line 44

The last time I made any changes in the Admin control panel, everything was working pretty good
