Thread:Project:Support desk/Some Special: pages won't display in version 1.22.2 Apache Win 7/reply (7)

This issue is reported at php.net bugs. On this report, it's caused when a require is done on a ntfs junction. That might explain why there are some entries on the debug log, until PHP hits that bug and apache comes with this odd message.

Maybe upgrading WAMP or using a different version of WAMP may solve this issue.
