So, I've got this ( probably really stupid ) problem that I just can't solve.
I have a really simple login script attached to an index.php page by including it in the header. Whenever I try to login chrome gives me this error:
The website encountered an error while retrieving <-Insert url here -!> . It may be down for maintenance or configured incorrectly.
Here are some suggestions:
Reload this web page later.
HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request.

The script works fine on localhost, the error is only shown when run on a paid webhost. Does anyone have an idea of what might be wrong?

What's your code?

Error 500 means nothing to do with php.

Are you using a .htaccess file ?

No, I am not.
And I only get this error when I submit the login form( it redirects from index.php TO index.php ).

/E I just realized I have the same problem when I use the Register form.

Can you post your code ?

Although I can't think of anything that would cause that, it might be worth contacting your host.

I have tons of sites running on that host, and none of them are having any errors.

The index page looks like this : [syntax=php]<?php
include('design/header.php');
?>[/syntax]

followed by some static HTML.

Header( I think the login is from your tutorials even ) :[syntax=php]<?php
/* Initialization */
include('core/init.inc.php');

$errors = array();

if (isset($_POST['username'], $_POST['password'])){
if (empty($_POST['username'])){
$errors[] = 'Du måste skriva in ett användarnamn.';
}

if (empty($_POST['password'])){
$errors[] = 'Du måste skriva in ett lösenord.';
}

if (valid_credentials($_POST['username'], $_POST['password']) === false){
$errors[] = 'Fel användarnamn eller lösenord.';
}

if(empty($errors)){
$_SESSION['username'] = htmlentities($_POST['username']);

Header('Location: index.php');
die();
}
}
?>
<html>
<body>
<td width='50%'>
<?php

if(isset($_SESSION['username']))
{
echo "
<table id='welcomeTable'>
<td>
<font size='2' face='arial'> <div align='center'>Välkommen, <b> ".$_SESSION['username']."</b>! <a href='logout.php'>Logga ut</a>
</td>
</table>";

}

else
{
?>
<form action="index.php" method="POST">
<table id="loginTable">
<tr>
<td>
<label for='username'>Användarnamn:</label>
</td>
<td>
<font size='2' face='arial'> <input type='text' name='username' size='16' maxlength='25'/><a href='register.php'>Registerera.</a></font>

</td>
<td>
<font size='2' face='arial'> <input type='password' name='password' size='16' maxlength='15'/> <input type='submit' value='Log In'/></font>
</td>
</tr>
</table>
</form>
<div id="indexPageLoginErrors">
<?php
if (empty($errors) === false){
?>
<ul>
<?php

foreach ($errors as $error){
echo "<li>{$error}</li>";
}

?>

</ul>
<?php
}

}

?>
</div>

</td>

</tr>
</table>
</td>
</tr>
<tr>
<td>
</td>
</tr>
</table>

</body>
</html>[/syntax]

Its probably something really silly. If it is, please don't rub it in my face

And please do ignore all the Swedish mumbojumbo. I did this site for a friend, and he totally refuses to have anything in english.

Well the code looks fine

(except the use of table and the font tag obviously)

[syntax=php]<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

</p>
<p>
<input type="submit" value="Go" />
</p>
</form>
</div>
</body>
</html>[/syntax]
You could try this on your host and see if it has the same problem, something else to try would be changing the names of the inputs (mainly username and password)

If the above script causes the problem, you will have to ask your host though.

Your script works just fine, and changing the input names makes no difference.
Tried this on 2 other hosts aswell, both have the same issue. So I doubt its server-side.
I think its in the code somewhere.

I've heard of people having trouble with sending headers when not using a full absolute path. Try redirecting to http://www.google.com/ and see what happens.

To be honest I doubt this is your problem, but it's always worth a shot, right?

Posted: **Fri May 06, 2011 1:05 pm**

Very odd problem.

Do you get redirected ? Or does the error happen before you get to that point.

It redirects me to google, and then it gives me an 405 error since I tried to pass my own $_POST info and it did not like that very much.

I do get redirected to the index.php, and THEN get the error message. Sometimes I even catch a glimpse of the site before getting shown the error message.

And its not just on my pc, I've had some friends try it and they all have the same problem.

Can you post the fill code of index.php then I guess it has to be something to do with that

Sure, but I really doubt that HTML, no matter how badly written, can crash a browser :S

Eftersom att jag går en linje där vi har datorinriktning så har vi webbdesign som ett ämne och då måste vi ju ha en hemsida där vi lägger upp uppgifter och sånt.
Anledningen till att "uppgifter" är lösenordsskyddat är för att jag inte vill att någon ska kopiera källkoder från mina uppgifter bara för att dom ska få det lättare i skolan, man får helt enkelt arbeta själv.
Utöver det så tycker jag att kodning är kul, så utvecklar sidan mer än vad som behövs hela tiden.

Irritatingly I have no idea then !

Are you sure there is no .htaccess file in your site root anywhere, they are generally hidden ? that's the only thing I can think of that would cause that problem.

There could be a hidden one, but It does not interfere with any of the 12 other pages I have on that domain. And how would I go about deleting/editing this hidden .htaccess file?

Via FTP or the web based file manager thing.

If it exists just rename it to see if it fixes the problem.

you may have to mess with the settings of your FTP client to get it to show up.

Alright, I'll try this.

Heading off to the gym now. Will try this when I get back. In the meantime, if anyone got any ideas. Feel free to post them!
