Fatal Eror! wp-admin/includes/template.php on line 504

In adding 1096 pages to a new install, somewhere I think a page ID has been corrupted. I’ve gone through and manually attempted to repair any missing page IDs but now I’m not sure if that was even the problem. It’s still not working.

I am unable to Manage Pages. When I attempt to even brows the pages I get Fatal error: Call to a member function on a non-object in [my site name]/httpdocs/wp-admin/includes/template.php on line 504

I’ve run the SQL table repair function and even added a couple of missing ID rows that were missing. Still no joy.

I can’t export out of WP but I do have the table data from MySQL.

What is the best way to recover from this point? Start over? Find some repair utility? Sort out the error message? I’m stuck.
