Thanks for the response. I’ve just tried deactivating and deleting as you’ve suggested, then installing the latest version, but am still having exactly the same issue with the download buttons no longer working in the new version. Example button shortcode is [wpdm_package id=1134 template="link-template-default-ext.php"]
I’ve reverted back to 3.0.97 again. Any other suggestions to identify/fix this issue?
