I have a BIG PROBLEM! HELP!!
In two days a have to present the website.

Yesterday I added some code (logo & text) to the copy of the template at:
/modules/system/templates/system_siteclosed.html
So far so good.

Later I added an revised logo and changed the text right above the login box. I turned the site “off” in admin. I logged out. Something went wrong, Very wrong. I probably inadvertently deleted or changed some line of code in the system_siteclosed.html file.

Trying to login today I get the “off” line page with my logo and text but when I enter my user name and pass nothing happens. The page just reloads!

When I try http://www.xyz.com/user.php. The page reloads! When I try http://www.xyz.com/admin.php the same thing!!
I’m out for good!!

Trying via PHPmyAdmin I must admit I am lost.
What can I do to get back?

Please HELP!

please do not double post, see my answer in your other thread.
