On FWHA you should refrain from using 6te.net - it is slow and generally unstable.
I have just had a report that FWHA is down? It appears to be the case. Welcome to the world of servers!
Read on.
You also do not have to use FWHA - there are many alternatives available. Part of the portfolio challenge is to open an account, upload your files, create a database etc. I purposely do not provide ALL the details on how to do it, since it is part of the learning curve. I am not going to feed you i.e. you just retype from examples
Doing it with EasyPHP or XAMPP on your PC gives you some experience... doing it on a server is just reading their documentation carefully.
Choose any other free web hosting service (see, you are learning already that there ARE free servers available!). Simply Google for "free web hosting PHP MySQL"
There are many other options. Just be sure you read their terms and conditions. They all have documentation/sections that explains it step by step. For example, you need to use the account at least once a month or it gets deleted.
