I have a website created by another developer, it is static site. I need to add a blog page to it. I am adding a link to the main navigation called blog, and then create a sub folder where I installed concrete5. I am using the greek yogurt theme and setting the page type to Blog_entry. When I click on the default for the blog_entry page type I get this error -
allowed path(s): (D:\;C:\PHP5;C:\Temp;C:\Windows\Temp) in D:\Inetpub\abc\blog\concrete\core\libraries\loader.php on line 422

Warning: file_exists() [function.file-exists]: open_basedir restriction in effect. File(D:\Inetpub\abc\blog\concrete/controllersD:\Inetpub\abc\blog\concrete/controllers/page_types/blog_entry.php/controller.php) is not within the allowed path(s): (D:\;C:\PHP5;C:\Temp;C:\Windows\Temp) in D:\Inetpub\abc\blog\concrete\core\libraries\loader.php on line 425

Could you please help me understand what am I doing wrong? and what can I do to correct the issue.
