Community PRO 3.1.3 solves an issue introduced in 3.1.2 which prevents the plugin’s permissions table from being populated. It only affected new installations, it did not affect upgrades. If you’ve installed 3.1.2 and have the issue, here’s how to solve it: Deactivate the Community PRO 3.1.2 plugin Overwrite all 3.1.2 files in wp-content/plugins/avchat-3-pro with the ones from the 3.1.3 archive (only insert_tables.php and avchat3.php changed) Drop/delete the community_pro_permissions and community_pro_general_settings MySQL tables Activate Community PRO 3.1.3
