Calling an custom field from theme option at the frontend

I’m not sure how you’ve decided to save your options but if I were to guess based on the code above, you’re saving your ‘aboutBlurb’ as an index in the website_options array which I also assume you’re saving in the actual WordPress Optionswebsite_options[about].

To get that data maybe try this:

$website_options = get_option('website_options');
echo $website_options['about'];
