Hello,
We’ve been using WPDM for several years on our website, with no headaches.
However, now on the front-end, when someone visits the download page it says “There has been a critical error on this website. Learn more about troubleshooting WordPress.” Below that text, it shows the header of the WPDM table, but no information.
We’re using the [wpdm_all_packages] shortcode, and that’s it.
I switched on PHP errors, and reloaded the page, and it shows the following….
Fatal error: Uncaught Error: Class ‘liveforms’ not found in /DELETED_SERVER_ADDRESS/public_html/wp-content/plugins/download-after-submit/download-after-submit.php:77 Stack trace: #0 /DELETED_SERVER_ADDRESS/public_html/wp-includes/class-wp-hook.php(292): liveform_for_wpdmpro->download_lock(”, Array) #1 /DELETED_SERVER_ADDRESS/public_html/wp-includes/plugin.php(212): WP_Hook->apply_filters(”, Array) #2 /DELETED_SERVER_ADDRESS/public_html/wp-content/plugins/download-manager/libs/class.Package.php(1000): apply_filters(‘wpdm_download_l…’, ”, Array) #3 /DELETED_SERVER_ADDRESS/public_html/wp-content/plugins/download-manager/libs/class.Package.php(1150): WPDM\Package::activeLocks(1331, Array) #4 /DELETED_SERVER_ADDRESS/public_html/wp-content/plugins/download-manager/tpls/wpdm-all-downloads.php(294): WPDM\Package::downloadLink(1331, 0, Array) #5 /DELETED_SERVER_ADDRESS/public_html/wp-content/plugins/download-manager/libs/class.ShortCodes.php(563): include(‘/DELETED_SERVER_ADDRESS…’) #6 /DELETED_SERVER_ADDRESS/public_html/wp-includes/shortc in /DELETED_SERVER_ADDRESS/public_html/wp-content/plugins/download-after-submit/download-after-submit.php on line 77
Any suggestions of how we can fix this error?
Hi
I have just found that trying to manage the memberships of any subscribers is not working at all and brings up a FATAL ERROR. See screenshot.
I have tried disabling every other plugin apart from WPDM and memberships and it is still giving me the same error. Also tried removing the membership plugin and installing again and same outcome.
Any help would be much appreciated

Installed Pro version on top of free version and getting error message below on attempt to activate plugin, any suggestions?
Fatal error: Cannot redeclare wfu_get_request_uri() (previously declared in /home/by2sa9r36x4v/public_html/wp-content/plugins/wp-file-upload/wordpress_file_upload.php:39) in /home/by2sa9r36x4v/public_html/wp-content/plugins/wordpress-file-upload-pro/wordpress_file_upload.php on line 53
Hello,
I have already installed basic pro version of the plugin Download Manager Pro v5.3.
Right now it is updated to version 5.3.5
And I have just bought your add-on WPDM Directory Add-on.
While trying to activate it from plugins page, it gives me an error :
Warning: require_once(src/init.php): failed to open stream: No such file or directory in
/public_html/assets/plugins/wpdm-archive-page/wpdm-archive-page.php on line 61
Fatal error: require_once(): Failed opening required ‘src/init.php’ (include_path=’.:/usr/local/php74/lib/php’) in /public_html/assets/plugins/wpdm-archive-page/wpdm-archive-page.php on line 61
How can I make it work?
Best regards
Thierry
