Sign-up page messed up with advanced search ?!

I suddenly found that when I tried to sign-up, the page was submitted as "advanced search". Can you help me to figure out the reason?

Btw, I installed: login side box, sagefish apple template.

......
.......

<fieldset> <legend>Newsletter and Email Details</legend> <input name="newsletter" value="1" checked="checked" id="newsletter-checkbox" type="checkbox"><label class="checkboxLabel" for="newsletter-checkbox">Subscribe to Our Newsletter.</label><br class="clearBoth">

<input name="email_format" value="HTML" id="email-format-html" type="radio"><label class="radioButtonLabel" for="email-format-html">HTML</label><input name="email_format" value="TEXT" checked="checked" id="email-format-text" type="radio"><label class="radioButtonLabel" for="email-format-text">TEXT-Only</label><br class="clearBoth">

</fieldset> </fieldset> <div class="buttonRow forward"><input src="includes/templates/d2/buttons/english/button_submit.gif" alt="Submit the Information" title=" Submit the Information " type="image"></div> ...... ......

I've figured the reason:

I changed 2 files under my template/templates/

tpl_login_default.php
tpl_modules_create_account.php

I was trying to remove the login box on the sign-up page which lead to that problem. Can anyone let me know what is the correct procedure to remove the login boxes on the sign-up page? I got the login side box and want to let the sign-up page a bit concise.

Thanks.

Change your link to go directly to tpl_create_account.php instead of to tpl_login.php

Got it.
