Hi David,

Sorry to bother you again.

I used the "Clean" template from Google and added below codes to file "create_account.php". I just put below codes on the top of the file(Before <?php)
<script type="text/javascript">
var RecaptchaOptions = {
theme: 'clean'
};
</script>

But when login or register, I got one blank web page. After refresh I could see content again but it is still at the login or register page. (Actually login or registed successfully becasue the "Logout" is shown on the top").

If I delete the codes above, everything is ok.

Do you konw what is the reason? Thanks very much!

Michael
