my problem with PDF Stamper v1.9 in combination with Download Manager v 2.9.69 that causes this error when trying to download a stamepd file:
Fatal error: Class ‘WPDM_Stats’ not found in /var/www/web28672525/html/www.felusch.de/wp-content/plugins/wpdm-pdf-stamper/wpdm-pdf-stampers.php on line 112
Workaround:
download the php file: wpdm-pdf-stampers.php
from the directory: wp-content/plugins/wpdm-pdf-stamper
and change the code in line 112 from: $log = new WPDM_Stats();
to: $log = new \WPDM\libs\DownloadStats();
save and replace the .php file on your server
good luck and I am not responsible for any trouble 🙂
…just want to share the solution with you!
