sorry that should be

mod/form/views/default/form/nav.php

I replaced

$_SESSION['last_search_qs'] = null;
$_SESSION['last_view_qs'] = $_SERVER["QUERY_STRING"];

$nav = elgg_view('form/nav',array('form_id'=>$form_id,'form_view'=>$form_view,'enable_recommendations'=>$form->allow_recommendations));

by

$_SESSION['last_search_qs'] = null;
$_SESSION['last_view_qs'] = $_SERVER["QUERY_STRING"];
print "Form id is $form_id";
$nav = elgg_view('form/nav',array('form_id'=>$form_id,'form_view'=>$form_view,'enable_recommendations'=>$form->allow_recommendations));

The message "Form id is 4" was showed. I added in the file mod/form/views/default/form/nav.php the code

print "I am here" after <?php

This last message is not showed.

What happens if you just comment out the

$nav = elgg_view('form/nav', ...)

line?

I commented the line

$nav = elgg_view('form/nav',array('form_id'=>$form_id,'form_view'=>$form_view,'enable_recommendations'=>$form->allow_recommendations));

and it works

ok, we are getting closer (but I think we still need the navigation).

Now can you put that line back, but comment out the switch statement in the nav view?

This bit:

switch($vars['form_view']) {
    case 'all':        $allselect = 'class="selected"';
                    break;
    case 'friends':        $friendsselect = 'class="selected"';
                    break;
    case 'recommendations':        $recommendedselect = 'class="selected"';
                    break;
    case 'mine':        $mineselect = 'class="selected"';
                    break;
}

Ah wait!

There is a

<? } ?>

on line 22 of that file.

Keep in the switch and replace that with

<?php } ?>

I think that we nailed it.

My PHP sees nothing wrong with that, but yours does I bet.

Blank page again.

The failure can be in

$url_start = $vars['url'].'mod/form/my_forms.php?id='.$vars['form_id'].'&amp;mode='.$vars['mode'];

Ah wait!

There is a

<? } ?>

on line 22 of that file.

Keep in the switch and replace that with

<?php } ?>

I think that we nailed it.

One moment...

Now it works!! Great!!

I am grateful to you for your help.

I have checked my code and that was the only place "<? " occurs without the php. It was just a typo that my xampp install ignored.

Thanks! I think all this was worth the effort.

I'll put the fix in my next release.
