My page do not display

Hi,

as 1st step enable this:

then you should be able to see more informations, white page doesn't help.

Let me know after.

Joomla core seems to be corrupted!

It even don't display article from default Protostar template.

Please check server Error Logs.

Contact with hosting support if you cannot find that file.

I have one theory. Your site was hacked (!) You have too many unauthorized files, infected. Here are evidence.

1. Have you added this content inside .htaccess file? I doubt.

2. Have you uploaded those files? I doubt.
