Hellow everybodi...

I succed to finish my first web site on local machine and i bought a host services and a domain name. After uploading files and mysql database I have only a huge blank page on index ....something it not wright....
Please help ....

Did you change data base settings ?

What did you used for php tags: whether it is <? ?> or <?php ?> .
For this <? ?> , we need to enable short tags in your server.

Is your website is having index.php or not?

Where did you uploaded your code (any sub folder)?

check for these basic validations.

I used <?php ?> , I have index.php, but output it blank page, I did not change my databse settings so this may be the problem...what I should change?

give your live database settings (where your database is located):
host,db username,db password,dbname.
give these correct details in the page where you have written connecting data base code.

I change the conection constants from the includes folder but I am not sure what to change at db_server...it still localhost...should I put the domain name the ip host ...or what? it an shared ip

ya, its is MySQL server IP.
or ask your hosting people , they will give you all these details.

These hosting people are not able to asist me. It a simple question that thei dont want to answer me. On phpmyadmin sais localhost . AT db_server should Y put localhost or the ip?
Sorry for this newbie ask but I am so fuzzy

Most servers place index.html above index.php so if you've made your home page as index.php and the host automatically puts an index.html page up, then it'll be displaying index.html. Have a look on your host and see if there is an index.html file and if so, delete it so that index.php is the one that gets called upon.

if the mysql server is on the same machine as your php code than localhost will most likely be your database server. If the mysql server is on a remote machine, you will need to use an ip or hostname and probably a port to connect.

In *most* hosting environments it will be localhost

Thank you man. The index.html was deleted still not working and I do not know if it realli from the database connection cause I change the script and no change even much more ...do you want to see the index.php code? Any ideas?

You've commented out all the code, that's why. Line 5, remove the /*.

/* is the start of a multi-line comment. To end it, you need to put */ at the end. If you want to comment a single line, you should use //.

Is error_reporting turned on?

<?php
error_reporting(E_ALL);

//rest of file
...

no error reporting
....I have no such thing ...can you give me some detail about?

**Didn't see the code posted. :icon_redface:
Borzoi looks to have nailed it with the comment.

<?php error_reporting(E_ALL);?>

Still no move it completely blank

<?php must be on its own line.

Remove the comment Borzoi mentioned and add error_reporting(E_ALL); below the php tag. Like what I posted above.

to post again the all page without comment marks?

I can not understand where is the wrong script...why no error show up?

I'm pretty sure session_start() should be before anything is outputted. You also have two <html> tags. Your first few lines should be like this:

<?php 
  session_start();
  error_reporting(E_ALL);
?>
<?xml version="1.0" encoding="UTF-8"?>

<?php include("includes/connection.php");?>
<title>PRIMA PAGINA</title>

done and same result....it outrages on my machine with wamp it ok ,,,,

Post the code you have now, with all the modifications.

<?php 
error_reporting(E_ALL);?>
<?php session_start(); ?>

What do you think doctor? It a medicine for this?

-You have no opening <head> tag.
-Remove the opening <body> tag on line 13.
-Move lines 15-33 into the body tag lower in the page.
-Move line 37 up so that is is in the <head> tag.

Just looking through the rest of it for any more errors.
