If you have this
$xoopsTpl->assign('xoops_showlcblock', 0);
$xoopsTpl->assign('xoops_showrcblock', 0);
$xoopsTpl->assign('xoops_showclblock', 0);
$xoopsTpl->assign('xoops_showcrblock', 0);
then you should find these variables in the list with Smarty debug.
If you have
<{if $xoops_showlcblock or $xoops_showrcblock}>
..
<{/if}>
in theme.html, the inside code (at the three dots) should not be showed/executed.
