Shamim's Plugins

Can you please share your website url?

You can use fep_add_announcement function

It seems you are using an old version. Can you please download latest version from account page and install?

1. You can add following code to set 2 urls depending on the user

add_filter( 'fep_query_url_without_esc_filter', function( $url, $args ){
    //Check here user and return url accordingly
    return add_query_arg( $args, 'https://example.com');
}, 10, 2);

Go to Front End PM PRO > Settings > Appearance > Load CSS file and set as “Always”
2. Announcements are sent according to roles. You can check to which roles you want to send announcements
3. follow https://www.shamimsplugins.com/docs/front-end-pm/getting-started/show-unread-message-count-in-menu/

Thank you for letting me know. I am still trying to figure out the conflict with WP version 5.7.1
After uninstall this plugin does not have any capability to create any issue. If you get that error message after this plugin uninstalled, That means that error is coming from somewhere else. You can give me the the error page link and i can try to find out where that error is coming from.

Can you please try only following code? (remove fep_admin_cap code)

add_filter( 'register_post_type_args', function( $args, $post_type ){
    if( 'fep_group' == $post_type ){
        $args['show_in_menu'] = true;
        $args['capability_type'] = 'post';
    }
    return $args;
}, 10, 2);

Let me know. This way you do not need to give other users admin access then modify by other plugin.
