I am on a dedicated server, and I have 2 blogs in each of their own subdirectories. They are setup identically, except for the skin, password, etc.

One of them generates constant errors in my server logs:

PHP Notice: Undefined property: Blog::$../custom/rdf_url in ...b2evocore/_class_dataobject.php on line 191

PHP Notice: Undefined property: Blog::$../custom/rss_url in ...b2evocore/_class_dataobject.php on line 191

PHP Notice: Undefined property: Blog::$../custom/rss2_url in ...b2evocore/_class_dataobject.php on line 191

PHP Notice: Undefined property: Blog::$../custom/atom_url in ...b2evocore/_class_dataobject.php on line 191

PHP Notice: Undefined property: Blog::$../custom/pingback_url in ...b2evocore/_class_dataobject.php on line 191

I compared this file in both blogs, and the line matches, yet I do not get the error on the 2nd blog.

Any help would be appreciated.
