I forgot... before installing the plugin form, I edited the function discussed above, thus the entities_subtypes tables for form are empty.

Hi Alcor,

Unless you can find a relevant reference to the problem in your error log, I have no information to work with.

As I said, this works just fine for me.

Blank pages reveal a PHP problem and it is strange that there is nothing in your error log.

There aren't errors with reference to my_forms.php, only with manage_form.php, as indicated above.

Trying one more option.

Do you have comments or recommendations turned on for the form you have created?

Comments and recommendations are turned off.

Hi Alcor,

Then without any new information from your error log, I am out of ideas.

Not only does this work for me but I looked through the my_forms code and could see nothing that could cause a blank page (eg. dependencies on other plugins etc.)

You could put prints in the my_forms code to get an idea of how far it gets before it crashes. That at least would provide more information.

Thanks Kevin for all your help.

If I understood good, I have to put some code to tell me where the error can be, right?  What code can I add, maybe an echo? I don't know...

yes, you can add lines like

print "I am here";

before and after every section in

mod/form/my_forms.php

to see how far it goes.

I use "print" for debugging statements to avoid confusing them with regular Elgg "echo" statements.

That way it is easier to find them and remove them later.

I've added your suggestion and I have been changing line by line until the message disappeared.

The print is not showed after the line:

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

Does this help you?

Can you put

print "Form id is $form_id";

above that statement and prints in

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

as well?

I see nothing in there but a switch and some echo statements, but at least it would be useful to see where it dies in there.
