Blank page after enabling compression

If i enable css or javascript compression in template advanced setings, i get blank page.

Hi

Please enable showing errors to maximum in global configuration of joomla and please let me know what error is shown. You may also need to rise the error showing level in php.ini file of Your server.

I allready did this. I have enable error reporting to max (in joomla) and php_value error_reporting -1 (in htaccess).
I get Internal server error 500 page, but no error is listed. No error in error.log in joomla, no error in server error logs.

I send request to server admin to enable in php.ini

Hi

Error 500 means that there is a problem on server side. Maybe it's because of lack of memory or wrong rights for the scripts and files cannot be created. Try exclude any outside scripts, maybe it cannot handle connection time. Really hard to tell error 500 can mean many, many things.
