JFactory::getDocument()->setTitle($item->title. ' - '. strip_tags

Salut clowride,
watch out for the first definition:

...
$item = $this->item;
...

In the default template, this definition block is followed by some CSS inline styles.

You might place your line after the definitions block.
Or even after the inline CSS block.
Just make sure it is inside php tags.

hello first thank you for your help i did but i already have blank page very strange

clowride i did but i already have blank page very strange

Right after inserting the new line?
Or did you make any other changes?

My quick test with default record template works. Tested 3 different fields and their ID's.

Excerpt from my template and position of the extra line:

...
defined('_JEXEC') or die();

$item = $this->item;
$params = $this->tmpl_params['record'];
$icons = array();
$category = array();
$author = array();
$details = array();
$started = FALSE;
$i = $o = 0;

?>
<style>
    .dl-horizontal dd {
        margin-bottom: 10px;
    }

.line-brk {
    margin-left: 0px !important;
}
<?php echo $params->get('tmpl_params.css');?>
</style>

<?php

JFactory::getDocument()->setTitle($item->title. ' - '. strip_tags($item->fields_by_id[20]->value));

if($params->get('tmpl_core.item_categories') && $item->categories_links)
{
    $category[] = sprintf('<dt>%s<dt> <dd>%s<dd>', (count($item->categories_links) > 1 ? JText::_('CCATEGORIES') : JText::_('CCATEGORY')), implode(', ', $item->categories_links));
}
if($params->get('tmpl_core.item_user_categories') && $item->ucatid)
...

Turn error reporting on, if you can't get back to a working page.

Thank you very good i did things like that but blank page and no error reporting :-( so strange

What it is strange is when i remove this line after blank page persist :-o

clowride blank page and no error reporting :-( so strange

Error reporting set to MAX should display something.

Anything else published on that particular page?
Replace record template with a fresh copy. Any difference?

Joomla blank page

Thank you Sergey and Pepperstreet i have this error Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/xxxxxx/public_html/index.php:2) in /home/xxxxxxxxx/public_html/libraries/joomla/session/session.php on line 665

Some fils you customized has whitespace in it. I think in index.php before <?php there is whitespace.

Sergey is on the right track. If you google your error, you will find a lot of similar posts/issues.
- either whitespace
- or wrong encoding of your file (or configuration file)
