Somewhere between the transient state of coding Xortify for XOOPS 2.6 the XOOPS 2.5 archive had a couple of files which had the XOOPS 2.6 code in it causing a White Screen of Death (WSOD). This is now fixed and you will be able to use Xortify to your hearts content!
If your running XOOPS 2.5 then download it from the files section in version 4.17!
Thanks
