Hello,
It should work, if not something else is interfering. I'm afraid it can't be fixed- I had to use a lot of tricks to get that to work at all.
What you could do as a work around is make a copy of register.php, put it where it is supposed to be, but in your .htaccess file deny anyone from loading the page except for your ip address.
Create (or add to) an .htaccess file:
Code:
<Files register.php>
Order deny,allow
Deny from all
Allow from 127.0.0.1
</Files>
Replace the red IP address with your own IP address.
Obviously the above is for Apache servers only. If on IIS or something else you'll need to figure out how to translate that to your own server, I'm sorry I have no idea how.
