Hi Sir,
Hope you are fine and well, I have tested your plugin in one of my domain, and I have installed a Plugin mentioned below;
URL: https://wordpress.org/plugins/user-access-shortcodes/
which provides a bbcode variable to protect required area of post from guest. But short code of this plugin is not working on your forum. Please fix that issue or make your forum plugin compatible with this plugin so I can use your wp-Foro
Please note all questions related to the free wpForo plugin should be asked in the wpForo.com community. Here we only support issues related to paid addons.
Try to enable the "WordPress Shortcodes in Post Content" wpForo option in the Dashboard > wpForo > Settings > Forum Settings admin page. If this doesn't resolve the issue, please create a new support topic on the wpForo.com forum.
This topic will be closed.
