I enabled the license, uploaded the plugin but somehow the bell is not showing via the shortcode. I tried adding this shortcode in the template, on a page, and on a widget, but it only shows the text of the shortcode.
[wpdiscuz_bell]
The settings are set to REST API/AJAX both, but no difference. Furthermore I do not see any settings to enable it or disable the plugin. What could cause this to happen? Also adding it via the menu (custom link) it says that the variable is not valid.
