It's realy important to me to get back access to my website studio. I can't give up. So i've tried again to upgrade for new version proceding like this :
Step 1: Download the version v2.1.6 zip file and unzip on your hard drive.
Step 2: Backup everything on your server!
Step 3: On your server, replace the folders "ndxzstudio" and "ndxzsite" (making extra sure you don't overwrite your /ndxzsite/config/config.php file)
Step 4: login to yoursite/ndxzstudio, you should see a yellow band on top with the message "update to 2.1.6", click on it and if everything went well, it'll show you a message that says that indexhibit is updated.
But i still have a log error, even by doing the retreive password process. So i can't complete the upgrading.
Could you please help me getting back some login password ?
