 * Hi Tim,
 * Will you do me a favor and swap out lines 248-250 in class-ctc.php
 * from:
 *     ```
       function check_theme_exists($theme) {
       return in_array(strtolower($theme), array_keys(wp_get_themes()));
       }
       ```
   
 * to:
 *     ```
       function check_theme_exists($theme) {
       return in_array($theme, array_keys(wp_get_themes()));
       }
       ```
   
 * and let me know if it fixes the issue. If so we’ll push a new version shortly.
 * Thanks for using CTC,
