* info field reorder

There was an extra error template for PHP warnings although there was
another template holding that already.
The status code check (500) is a step that would make sense for all of
the checks. This is not limited to warnings. Though I think that error
code 500 shrinks the result set too much in this case. That's why I
would leave it out.
