I have over 20 items in database. I have set in option that 20 should be shown
in the list. The HTML for pagination looks like '<div
class="pageshowrows"></div>'. When I change on 'itemtab.tpl" line '<div
class="pageshowrows">{$pagination}</div>' to '<div
class="pageshowrows">{$pagination|var_dump}</div>', I get the following HTML:
<div class="pageshowrows">bool(false)
</div>.

By changing item count on page to 50, I can get list of all items, so this is
not critical.
