 * Fatal error: Call to undefined function: get_header() in /home/lukehack/public_html/
   fruitpants/index.php on line 1
 * Okay, my site is here: lukehackney.com/fruitpants
 * This error came up after attempting to install a theme. I tried going back to
   an old theme, but this keeps coming up. Don’t know how to fix it, where it came
   from, etc.
 * Any suggestions? I’m rocking v. 1.5. You can email [lukehackney@gmail.com](https://wordpress.org/support/topic/undefined-function-2/lukehackney@gmail.com?output_format=md),
   answer here, or talk to me via aim (luke hackney).
 * Thanks.
