Moved Wordpress to Test Site URL not Working

I'm currently having an issue on my website at cjcdigital.net/katrina where I tried moving it over to test a new theme however when the user clicks any of the links in the site, it takes them to the original URL (katrinaeugenia.com)

I tried changing the URL in the PHP database wp_options table however that doesn't seem to fix all the links.

Any assistance is appreciated.

Best,

Charles
