 * Hi.
 * I’m having an issue when I try to use Mooberry as a Widget. It works fine for
   Random, Newest, and Future Book, but when I try for a Specific Book it throws
   out this error:
 * **Warning**: Undefined array key “mbdb_bookID” in **C:\xampp\htdocs\megchronis.
   co.za\wp-content\plugins\mooberry-book-manager\includes\class-mbm-book-widget.
   php** on line **89**
 * **Warning**: Attempt to read property “ID” on null in **C:\xampp\htdocs\megchronis.
   co.za\wp-content\plugins\mooberry-book-manager\includes\class-mbm-db-books.php**
   on line **101**
 * I’ve spent the last couple of hours trying to figure this out. What am I missing?(
   I’ve obviously tried selecting the specific book I want)
   WP is 6.1.1, and PHP
   is 8.2.0
 * Thanks

 * I am so sorry this response is so late! I did not receive notification of this
   message and am just seeing it now. I’m going to look into it right now!
