I have exactly the same problem.
My page was working OK and suddenly stopped retrieving any information.
I have tried to change and build the page on another wordpress site with exactly the same result: no data found.
This is the page url: http://www.gtconseils.com/bdor
The virtual post test says: “This test URL matches 72 records in table Test maquettes”
The virtual post is linked with the page bdor
The code in the page is:
[apr_loop]
<h1> ID: {{Test}}<br /></h1>
<b>Action: </b><b>{{Action}}<br /></b>
<b>Remarque: </b>{{Rem}}<br />
[apr field=’Ecran|url’ glue='<hr>’ wrapper=’
‘]<br /> <hr>
[/apr_loop]
