 * Hi. In the latest two versions I got this error on my client’s website:
 * **Fatal error**: Uncaught TypeError: stripos(): Argument #1 ($haystack) must 
   be of type string, array given in /wp-content/plugins/stackable-ultimate-gutenberg-
   blocks-premium-c/pro__premium_only/src/conditional-display/post-meta.php:76
 * And I had to fix it myself like this:
 *     ```wp-block-code
       if ( $operator === 'contains' ) {
                       if(is_array($value)){
                           return stripos( $value[0], $expected ) !== false;
                       }else{
                           return stripos( $value, $expected ) !== false;
                       }
                   }
                   if ( $operator === 'does-not-contain' ) {
                       if(is_array($value)){
                           return stripos( $value[0], $expected ) === false;
                       }else{
                           return stripos( $value, $expected ) === false;
                       }
   
                   }
       ```
   
 * Please consider applying it in the next version. Thanks.
