500 Internal Server Error when trying to create an account

I am trying to create an account via the dashboard, when i try clicking Proceed / Continue after entering the sub-domain and password, the page loads for 1 minute and then gives me a 500 Internal Server Error, the entire ProFreeHost website then stops working until i refresh the cache.
This has been happening for the whole day now and it has yet to be fixed on my end, I'm not sure if this is happening for anyone else, but i would like to know what can be done to fix this issue.
