JOOMLA 2.5.8
VIRTUEMART 2.0.14
PHP 5.3.18

I can't find Joomla Error, i activate the visualization of error but doesn't see nothing, the page is blank.
On the frontend the site is working, i have the problem on the backend

The site www.trendsrl.net/shop is the site with error

If i close the browser and re-open it, the product backend works until i change pagination or i do some operation that seem's go in timeout. The page became blank after some second where the system doesn't do nothing

I try but doesn't work.

I modify the .htaccess because i can't access directly the php.ini file

On chrome the error is

Errore HTTP 500 (Internal Server Error)

Hello,

Sound like an apache error, can you rename the .htaccess to htaccess.txt

[flaterik]

Nothing change.
If i change the pagination from 20 to 100 , sometimes work, but when i put 400 doesn't work

Hello,

Can take a look inside joomla error log? Also can you check apache error log? You run it locally or on a server?
Any live url?
