mononet.com.ar

THANS, I COULD FIND THE SOLUTION!
I IMPORT MI BACKUP SECURITY FILE SQL TO MY SERVER HOST WHIT PHP ADMIN.
THANI REPLACE THE INDEX.PHP FOR THE OLD INDEX.PHP IN MY ROOT FOLDER.
EVERYTHING IS GOOD NOW I GO BACK TO THE OLD SITE. (INDEXHIBIT VERSION 0.73)
BUT I STILL HAVE TOO MANY DOUBTS AND QUESTIONS FOR THE NEW INDEXHIBIT TWO.
THANKS A LOT FOR YOUR TIME!
HAVE A NICE WEEK!
