Zen-cart login admin

Good Day!

Anybody would like to help me. There is an error in logging to my admin
to be able for me customized my website. Below is the error.

Thanks in advance.

Warning: require(includes/application_top.php) [function.require]: failed to open stream: Permission denied in /home/susan/public_html/estore2/catalog/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/susan/public_html/estore2/catalog/admin/index.php on line 23

Try reloading the files for:
/admin

to your server to ensure that you do not have and bad, missing or otherwise corrupt files ...

thanks, i was able to reload the admin files. but still a minor problem, how can i
view the main admin login page. All i can view is the index or directory of the
admin pages.

thank you in advance.

If the you go to:
http://www.your_domain.com/admin

and get a directory listing, then you are either missing files and need to reload the /admin ... or your site is not setup properly to run php files ...

Oh! I upload all the files again from scratch. But i still have errors that the index.php is not viewable or not available. So i will upload all the files again?

Help!

thanks again......

Try renaming your directory:
/admin

to /admin_BROKEN

Now reload the /admin directory and all subdirectories and files ...

Then copy the file:
/admin_BROKEN/includes/configure.php

to the new directory:
/admin/includes/configure.php

If it still does not work, try going to it specifically:
http://www.your_domain.com/admin/index.php

If it still does not load, contact your site and see if you even have php working properly on your site ...
