ok, found it from 1.0 post.
Here's the trick in case somebody have experienced the same issue.
Edit your comprofiler.html.php, go to registerForm function, about line 1263, below this,
[code:1]
...
<div style="align:center;" id="cbIconsTop">
<?php
echo getFieldIcons(1,true,true,"","",true); // to remove top icons explanation just comment or remove this line
...
[/code:1]
just add a condition,
[code:1]
if ($mosConfig_sef=='1') $linkAct = $mosConfig_live_site."/component/com,comprofiler/"; else $linkAct = "index.php?option=".$option;
[/code:1]
and change the form line into,
[code:1]
<form action="<?php echo sefRelToAbs($linkAct); ?>" method="post" id="adminForm" name="adminForm" onsubmit="return submitbutton(this)">
[/code:1]
and one more for lostPassword function I guess also need this trick.
hope this will help others who also used the 'Just History' OpenSEF.
