How to change URL that header links to

Hi Sakin, hope this is a quick and easy question: After using these instructions to migrate my (Simple Catch themed) site from pmcsconsulting.com/dev to pmcsconsulting.com, I have just one problem: The header on all pages still links to pmcsconsulting.com/dev. How can I make it link to pmcsconsulting.com? I know from looking at some of these articles that editing the child theme's header.php file might be the answer, but even when I go into that file, I can't find the code that the articles say I should edit. THANKS in advance for your help!
