Hi darsh !
You open index.php file in templates/ja_genista folder , find section code :
<?php if ($tmpTools->getParam(JA_TOOL_USER) & 4) { ?>
<div id="ja-usercolorswrap">
<div id="ja-usercolors" class="clearfix">
<?php $tmpTools->genToolMenu($tmpTools->getParam(JA_TOOL_USER) & 7, 'png'); ?>
<ul style="margin: 0; padding-left: 10px;">
<li><a href="#Top" title="Go to top" style="text-decoration: none;"><img src="<?php echo $tmpTools->templateurl();?>/images/top.png" title="Goto top" alt="Goto top" /></a></li>
</ul>
</div></div>
<?php } ?>
change into :
<?php //if ($tmpTools->getParam(JA_TOOL_USER) & 4) { ?>
<div id="ja-usercolorswrap">
<div id="ja-usercolors" class="clearfix">
<?php $tmpTools->genToolMenu($tmpTools->getParam(JA_TOOL_USER) & 7, 'png'); ?>
<ul style="margin: 0; padding-left: 10px;">
<li><a href="#Top" title="Go to top" style="text-decoration: none;"><img src="<?php echo $tmpTools->templateurl();?>/images/top.png" title="Goto top" alt="Goto top" /></a></li>
</ul>
</div></div>
<?php //} ?>
then try to set again in admin !
