Sorry for the late response,
after some searchs i found that "$smarty.server.PHP_SELF" the absolute location from the root of the website - not the root of xoops but the root of the host folder
to have an example of it put - in local of course -
<{$smarty.server.PHP_SELF}>
in the theme.html file and see what it give for the page you want
EX for my local
/~amine/htdocs/modules/wfchannel/index.php?wfc_cid=2
so for me i must put
<{if $smarty.server.PHP_SELF!='/~amine/htdocs/modules/wfchannel/index.php?wfc_cid=2'}><{$xoops_block_89.content}> <{/if}>
if it work do the same trick to your website
