Looks to me like a header is trying to generate an image, but you have left out an i.
Why your using a DNS query...for an image creation in a header.
I haven't the slightest.
Also, why are you trying to upload xampp stuff onto this server?
if you are not...then that means your testing local system...and you may need to reinstall your version of xampp.
best of luck! hope this helped.
