Replied by visionears on topic Delete item from frontend - front end delete article
We had the same problem with some clients. Mostly when we create a site for a client we only give them frontend access. I think frontend deleting items should be included in the components too.
Workaround
I created a piece of code that makes it possible to delete items from the frontend. You need to install Jumi for this solution, please ensure you have a newer version (e.g. 2.0.6). After the installation of Jumi you can paste the code below in a Jumi Module and publish the module somewhere in your template (e.g. above the <jdoc:include type="component" /> tag.
The delete function can only be used by Managers, Administrators and Super Administrators. If you want other frontend users to be able to delete items you should edit the first if statement.
This piece of code was tested with Joomla 1.5.21 with Flexicontent 1.5.3c.
Hope this will help some people

$cid = JRequest::getVar('cid', null);
$delete_item = JRequest::getVar('id', null, 'post','int');
$view = JRequest::getVar('view', null);
if($option == 'com_flexicontent' && $view == 'items' && is_numeric($delete_item)) {
$delete_items[] = $delete_item;
$link = 'index.php?option=com_flexicontent&view=category&cid=' . $cid;
if(delete($delete_items)) {
$mainframe->redirect($link, 'Item deleted', 'notice');
} else {
$mainframe->redirect($link, 'Item not deleted', 'error');
}
} elseif($option == 'com_flexicontent' && $view == 'items') {
echo '<form id="delete_item" name="delete_item" action="" method="post">
<input type="hidden" name="id" value="' . $id . '" />

<input type="button" class="button" value="Delete item" onclick="if(confirm(\'Are you sure you want to delete this item?\')) this.form.submit(); else return false;" />
</form>';
