Ok thanks for your interest. I've been doing some tests but no luck.
1- My website only on contains item views, so I can't say about category views.
2- No fields at all, core AND custom.
Note : On my custom templates, the "hide main text field" is turned ON (in the backend Type page, right column, second option after "content template"). I tried to turned it off and add some core fields in the template but still no luck.
3- All templates are custom. Fields are called this way:
Code:
<?php echo $this->fields['myfield']->display; ?>
4- I tried to apply the default template (item) to one of my content, and add custom fields to the code. Core fields are displayed, but not custom.
5- Indeed, after re-saving the module conf I was able to see the core fields, but custom fields do not appear.
I can provide an akeeba backup of the site if you need it.
Thanks a lot.
