Thread:Project:Support desk/installed 1.20.3 is ok, but wiki seems not to work except mw config/reply (4)

You do not get a PHP error.

When you call the domain directly, then you get a 301 redirect to index.php/Main_Page. So far so good.

But when you call index.php/Main_Page, then you get exactly nothing. Not even HTTP header data is sent.

Do you maybe have reqwrite rules in .htaccess, which could cause this?
