When you delete an question/answer in a category, the rest of the questions and answers dont display properly until you exit the category and re-enter. The problem appears to be in admin/index.php in the delcontent code on thle line:

xoops_confirm(array('op' => 'delcontents', 'id' => $id, 'ok' => 1), 'index.php', _XD_RUSURECAT);

You need to add the "cat_id" in to pass to the listcontents code. Which makes the line:

xoops_confirm(array('op' => 'delcontents', 'cat_id' => $cat_id, 'id' => $id, 'ok' => 1), 'index.php', _XD_RUSURECAT);
