File Manager Error line 178, 179

[grandpas]

I just installed oscommerce, and was doing great until I tried to acess the file manager through control panel.

I get the following error:

 

Warning: dir(path to my root directory.com/): failed to open dir: Permission denied in /path to my root directory.com/admin/file_manager.php on line 178

 

Fatal error: Call to a member function on a non-object in /path to my root directory.com/admin/file_manager.php on line 179

 

Can anyone please help me???

I forgot to include the lines...

 

178: $dir = dir($current_path);

179: while ($file = $dir->read()) {

 

 

I'm absolutely lost...

Please help!
