I spoke to soon. Now I can't get back in. I'm using Firefox but the same thing happens in IE. Is there supposed to be a redirect when I authenticate? If so then that's not happening. As I stated earlier when I use the correct username and password and press login, I just get this string in the address bar following the domain name "/Admin/index.php?accesscheck=%2FAdmin%2Fhome.php". The username and password fields clear also. Not sure if it's a cookie issue or something else. The trick I tried earlier didn't work the second time.
As for GST and ABN, the Australian Tax Office require that a registered business have an ABN or Australian Business Number. GST is a Goods and Services Tax which is 10% and I know I can set that rate but if we are going to generate a Tax Invoice it will need to show the ABN and GST. That's why I was wondering if there is a hack or someway to add it to the program.
