Today I updated to Version 3.1.15 and now received the following errors.

WP Version: 5.6.1
PHP Version: 7.3

Error Message:
WordPress database error: [Table ‘mysite.wp_ahm_user_download_counts’ doesn’t exist]
select download_count from wp_ahm_user_download_counts WHERE user = ‘6’ and package_id = ‘30820’

Notice: Undefined index: terms_page in /www/mysite_823/public/wp-content/plugins/download-manager/libs/class.Package.php on line 218

Please deactivate and then reactivate the plugin, that will update the DB table and fix the issue.

I deactivated the plugin, cleared cache, and reactivated.

Upon reactivation this notice appeared at the top of the Dashboard page:
“The plugin generated 478 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.”

On the page with the File Download this message still appears
“Notice: Undefined index: terms_page in /www/mysite_823/public/wp-content/plugins/download-manager/libs/class.Package.php on line 218”
