So, on the plugin on my site, I am getting an error message like this whenever I try to access the pages for the subscribers:
Fatal error: Class 'Subscribe2_List_Table' not found in /mnt/target06/346262/394688/www.aspenreallife.com/web/content/wp-content/plugins/subscribe2/admin/subscribers.php on line 136
I've downloaded a fresh version of the plugin and tried to re-upload it. When I do that, and refresh the page, I do not see the error message - but only for a second. If I refresh the page again, then I get the error.
