Active Server Pages error 'ASP 0126'

Include file not found

/application/unprocessed_application.asp, line 56

The include file '../../_fplclass/pdblib.inc' was not found. 

Answer 1

The path to pdblib.inc is outside of the document root for your site based on the path /application/unprocessed_application.asp. Make sure you have parent paths enabled on the new server, it is disabled by default in IIS6.

In IIS Manager,

1. Right-click your web site and click Properties
2. On the Home Directory tab click the Configuration button
3. Click Options and then make sure Enable Parent Paths is checked

EDIT:
You'll also get this error if you're using and #include virtual=<path_to_file> instead of #include file=<path_to_file>
