IMPORTANT NOTICE FOR PRO USERS: After you upgrade to 3.0.0 from an old version, you will notice that WordPress has deactivated the plugin due to an error: ‘Plugin file does not exist’. This is because we have renamed the pro plugin folder name from “advanced-db-cleaner” to “advanced-database-cleaner-pro”, causing the WordPress to not being able to find the old one and therefore deactivating the plugin. Just activate it again. It doesn’t break anything. Once you activate the plugin again it will continue working normally without any issues. You will also probably lose the pro version after this upgrade (This is due to a conflict between the free and pro versions which is now solved).
