I updated to the new current version and my extra fields using the own article format stopped working. I went back to the old version and all is well again,
My own article format code is this:
<div class="ukNewsPro">
<h3><a href="{URL}">{TITLE}</a></h3>
<span>Duration {{DurationoftheTrip}} Days, From {{price}} p/p</span>
<a href="{URL}"><img src="{IMAGE_SRC}" alt="{TITLE}" /></a>
<p>{TEXT}</p>
<a class="button" href="{URL}">Read More</a>
</div>
Obviously 'price' and 'DurationoftheTrip' are defined extra fields in K2. I have double checked that the "Get K2 Extra Fields" is set to yes and the "Article Format" is set to None Selected. Just replacing the module code fixed it, left the new admin code alone, my bad but this site is not live yet.
Resulting output when it works attached and when it fails.
All current version Joomla, due in production in about a week. Can PM the site url and details.
