Yes upgraded would be an option, but I didn't want to do it, because my Starter Plan was just for testing purposes, to evaluate the TCH services, etc.
There wasn't anything valuable there, so I needed a new plan to host my site anyway.
BTW I think this is a really cool way to test something .. buy 1 month of Starter Plan, mess it up somehow (if you are like ne, totally new to web hosting), and learn the correct way to do it on your "live" site.
I have been deceived 1-2 times in "cheap" web hosting plans, in which you must pay for a hole year for example 15-20 $, then after 2-3 months they say to you you must prepay for the 2nd year, and then .. dissapeared !
One of the most great things of TCH is that offers the 1 month payment in their Starter Plan, something that other companies don't (you must pay a hole year even if you don't use it ), and you can easily test / evaluate TCH services.
Anyway guys thanks for your replies
