Why? 
Where should I copy index.php file in ftp?
Just to the ftp root directory where MySQLadmin/ PgSQLadmin/ or filemanager/ are located
You should transfer your index file to your root directory, if you dont know where is the root, just type / in the ftp login path,… and then check your web by reloading the browser
I uploaded index.php into /filemanager and all directories, even into the main directory, but I can’t see the mainpage yet…
http://meka.bplaced.net/filemanager/ → „under construction“
http://meka.bplaced.net/users/meka/www/ → „under construction“
http://meka.bplaced.net/www/ → „under construction“
Assuming that „under construction“ is the content of your index.php, it shows up everywhere you put it …
If you want it to show up when you visit http://meka.bplaced.net/ - then you should put it in your FTP root folder, not into subfolders.
Now, it’s ok… Thanks for help…
