Hi,
thank you for return
Yet I am not the only one with the problem.
I saw another topic that speaks after posting mine
https://www.joomlart.com/forums/topic/ja-bookmark-plugin-with-virtuemart-2/
And update after not work too!
To resolve I had to apply this tip (page 2)
OK, better than giving you credentials, I have tried to figure out by myself
So in k2category.php around line 109 you changed "element" to "name"
was :
SELECT COUNT(*) FROM #__extensions AS e WHERE e.element ='$component' AND e.enabled=1
now is :
SELECT COUNT(*) FROM #__extensions AS e WHERE e.name ='$component' AND e.enabled=1
So, in vmcategory.php, I tried to also change "element" to "name"
Was :
->where($db->quoteName('element').'='. $db->quote($component));
Now is :
->where($db->quoteName('name').'='. $db->quote($component));
… and yessssss ! now it works fine : no error message (cf screenshot I sent).
But how comes that "element" works on some sites and that it has to be renamed "name" for other sites ??
(because I have installed and tested the latest JA Bookmark, the same version, on a fresh test-site done on demojoomla.com, and there it would work fine, even without renaming "element" to "name" !)
