I have hit a brick wall if you read this thread:
You will get a better understanding. I really thought this issue was somehow tied to the Mac OS Tiger vs. Leopard (Using a MacBook Pro, MacBook Dual Core and the new MacBook Air) but its not it happens on all three?
I have successfully installed and is working perfectly and can upload from all three Macs in Tiger and Leopard using FireFox and on any PC I have tried Windows XP and Vista.
When I even attempt to log-in to my PhotoPost website using Safari on either OS I can not even put in my Username before it jumps back to the main page and doesn't allow me to even log-in to the PhotoPost website!
Here is my site http://www.virginiaphotographer.net
If any Mac users out there can attempt to register and log-in successfully I would be curious to know if you do!
As Chuck mentioned in the thread above he doesn't have a Mac to replicate my problem and its just so strange its only doing this in the Safari browser, I have combed all the settings in Safari and just see nothing I can change to even try and make a difference.
