Removing the hook sorted it nicely. Thanks for that.

Just upgraded from 1.2 build to trunk so we can take advantage of Windows 10. Everything completed with no errors when running ./install.sh However when accessing the web site to update the database all you are presented with is a blank web page.

Output from httpd error log
