I have installed this extension : http://www.opencart.com/index.php?route … on_id=6874

This extension sends a verification link to email which is submitted in the customer registration form. After clicking the link, this extension automatically approves the customer.

I have no problem in the function of this extension. When i click the link it is approving the new customers.

If i click the link again it should redirect to home page of the site, but it is giving an error message

Notice: Undefined index: verification_code in /home/booksphb/public_html/catalog/controller/account/verification.php on line 17Warning: Cannot modify header information – headers already sent by (output started at /home/booksphb/public_html/index.php:106) in /home/booksphb/public_html/catalog/controller/account/verification.php on line 18

Site Url : is bookswordy dot com

Verification link : http://www.bookswordy.com/index.php?route=account/verification&v=df7d50ef3ad49a89b3889998831e76c3&u=8

I have tested this in my dummy site there it is redirecting automatically. i dont know what is the problem.

Dummy site : http://viceroysexporters.com/test/

Verification link : http://viceroysexporters.com/test/index.php?route=account/verification&v=ec109bd047d17e2f08765e905239ade7&u=12

i dont know where i made mistake.

Both sites are in shoppica2 and opencart 1.5.5.1

Please provide some advice.
