[Plugin: DB Toolkit] Fatal error: Class 'PDFReport' not found in../wp

Dear David,

I do get the error when I do create an entry and when I want to export it in .pdf format I do get the following error:
Fatal error: Class ‘PDFReport’ not found in ../wp-content/plugins\db-toolkit/plugincore.php on line 673

Thank you.

Kind regards,

Maramk
