Admin URL stopped working

[Selmer]

I can't login to my admin page anymore. It just stopped working. I can't understand why.

It says HTTP 500 - problem with server...

So the URL that used to make me login is now just showing nothing. And I've checked with the admin file name and it is the same as it was Before and the URL is the same as the file name is...

 

I also have orders that I cant access... Can I access my orders through file management?
Does anyone know how to get a proper URL or knows what may be causing this problem?

Best regards

a simple search would have informed you to enable PS debug mode...so make sure to learn to do this when 500 error,  you will need to enable via ftp...

once you collect the info of error, post it here...(but it's MUCH better to post originally)...

Thanks El Patron. Now I can see the following:

But I still don't know what to do?
I'm not experienced with these kinds of problems.
Do you have any idea of what I can do?

I did nothing but it has now been changed to this:

This did not work though, I needed the full wp-login without the re-direct section, simply make sure the website URL is configured correctly prepaidgiftbalance.
