I am trying to: add some new views to a layout but if I add any other view the page does not diaplays and I get the following message:

Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0

If I remove that view the page renders correctly

The page without the additional view is: hidden link

Addina any other view to this page gets the fatal error message. We tried with a relationship post view, a map view and the result is always a fata error.

What can be the reason?

Usually this error is cache-related. Have you tried disabling all non-Toolset plugins and activating a default theme? Please try that first, and check to see if the error is resolved. If so, reactivate theme and plugins one by one until the conflict is revealed. If not, please turn on server logs and see if any additional information is provided in the error log.

Go in your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:

define('WP_DEBUG', true);

Then add these lines, just before it says 'stop editing here':

ini_set('log_errors',TRUE);
ini_set('error_reporting', E_ALL);
ini_set('error_log', dirname(__FILE__) . '/error_log.txt');

Reload the page that causes the 500 error. This will create an error_log.txt file in your site's root directory. Please send me its contents. Once that is done, you can revert the changes you made to wp-config.php.
