Hello,

I use ZOO + APP in my site.

plugins simgenealogy_system.php
we use ajax on my site. So when an ajax call is made then this is in your code:

if (!$wrapper) {
$document->setBuffer($buffer . '

', 'component');
}
And this adds extra code in our ajax call. and breaks the ajax result
the error explained above :
