    What are the settings of these plugins?
    Do you have custom code (e.g. email to, condition, attachement...)?

    Hi Troester,
    NO there is no condition, no attachement, no template article ....
    Only text with placeholder

    The error occurs even with a simple redirect to homepage ....

    Can you set error reporting in Joomla to maximum and enable debug mode, and see if you get a more informative error message including the file name and line number.

    so, in list view :
    Warning: Division by zero in my path site root /form/plugins/fabrik_element/calc/calc.php(313) : eval()'d code on line 1

    in form/detail/add view :
    Warning: Division by zero in my path site root /form/plugins/fabrik_element/calc/calc.php(104) : eval()'d code on line 1

    Then on debug mode at the and of the page there is :
    SELECT b.id

    FROM l7w43_user_usergroup_map AS map

    LEFT JOIN l7w43_usergroups AS a
    ON a.id = map.group_id

    LEFT JOIN l7w43_usergroups AS b
    ON b.lft <= a.lft
    AND b.rgt >= a.rgt

    WHERE map.user_id = 524
    id select_type table type possible_keys key key_len ref rows filtered Extra
    1 SIMPLE map ref PRIMARY PRIMARY 4 const 2 100.00 Using index
    1 SIMPLE a eq_ref PRIMARY PRIMARY 4 avis2sante_telemedicine_joomform.map.group_id 1 100.00 NULL
    1 SIMPLE b ALL idx_usergroup_nested_set_lookup INDEX N'A PU ÊTRE UTILISÉ NULL NULL 15 100.00 Range checked for each record (index map: 0x10)

    Thanks for helping

    Well ...

    ... means you have an error in your code in a calc element, so first step is to fix that. You need to make sure whatever you are dividing by has a value. So, say you are using a placeholder to get the value of an element you will be dividing by ...

    Code (Text):

    $myValue = (int)'{yourtable___yourelement}';
    if ($myValue !== 0) {
      return $something / $myValue;
    else {
      return 0;

    Hi Cheese,
    Ahah! you're right, but strangely before update I didn't get this error !!!
    As, I don't have this on my second server !
    I take a look about that, I think there is something else

    And I have another question, so : new thread...

    I repeat the form plugins work great in other forms, just this one. As I add a form plugin (redirect, mail, ....) I get this error
    For sending mail I use :
    One default field with : $user =& JFactory::getUser(); return $user->get('email');
    And a calc field with :
    $expertId = '{a2s_dossier_expertise___nom_expert_raw}';
    $myDb = JFactory::getDbo();
    $myQuery = $myDb->getQuery(true);
    $myQuery->select('e_mail')->from('a2s_users')->where->where('id = ' . $myDb->quote($expertId));
    return $myDb->loadResult();

    {a2s_dossier_expertise___nom_expert_raw}'; :
    Databasejoin (a2s_users) with concat label : nom,' - ',pro_firstname,', ',specialite_list

    the data are well set in the list.
    but the worst is that even with a simple redirect formplugin it doesn't work.
