Hi, I spent some time looking at the error messages, but did not find the one I received. Zen Cart installed OK. The area for index page is working OK, but when I tried to go to the admin area to make a changes I got this error message.

Warning: require(includes/application_top.php) [function.require]: failed to open stream: Permission denied in /home/sofi297/public_html/store/admin/index.php on line 23

Fatal error: require() [function.require]: Failed opening required 'includes/application_top.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/sofi297/public_html/store/admin/index.php on line 23

I am new and not a programmer. Would anyone be able to tell me how to repair the problem? I would sure appeciate any help.

Thank you for any help.
Sofi.
