 * I have websites that keep giving new users this error when they sign up using
   S2Member from paypal:
 * ERROR: Unable to verify $_SERVER[“HTTP_HOST”].
    Please contact Support for assistance.
 * If you are the site owner, please check the custom value in your Button Code.
   It MUST start with your domain name.
 * I have tried to find a solution to this issue but i have not been able too, it
   also only does this once in a while, sometimes it works just fine then other 
   times there is nothing but issues. I hope i can get an answer on how to fix this.

 * People are still not being redirected, it has gotten better with more people 
   being able to sign up, but some are still not being sent to the registration 
   page.

 * If it has gotten better, then that’s either a happy coincidence, or a product
   of the change you made. If the latter, then raising the memory level more should
   help more, so I’d try using this instead of your current first line above in 
   wp-config.php:
 * `define('WP_MEMORY_LIMIT', '96M');`

 * Ok i upped the memory again, if that doesn’t work what else could it be? This
   plugin is really starting to be a pain.

 * I don’t know what else the problem could be, but my guesses would relate to PayPal(
   they are always changing things) or your host. Certainly, if increasing memory
   does improve things, my money would be on your host.
 * If you’re running the Pro version of s2, you could contact Pro support at s2member.
   com/contact and see if Cristian and the others can figure it out.

 * Yeah i would be nervous on paying for this when the free version doesn’t even
   work correctly, Thanks for your help!

 * The members section is working good now that the memory had been increased, but
   now regular PayPal buttons that have nothing to do with the members section seem
   to be getting this HTTP error now, this has not happened before.
