To use in announcement email you will need to add announcement in where.
When using fep_get_the_content hook, if mgs_id is not available use fep_get_the_id()

Let me know.

You can follow https://www.shamimsplugins.com/support/topic/can-we-rename-message-box-to-inbox/#post-11735

First remove group settings from user settings page using following code

add_filter( 'fep_form_fields', function( $fields ){
    unset( $fields['fep_groups'] );
    return $fields;
}, 99);

Then show a form where you want your users can set their groups. You can get all groups using Fep_Group_Message::init()->get_all_groups() and user selected groups using Fep_Group_Message::init()->get_user_groups(). When they submit their form determine if they added or removed any group and save value accordingly.
You can get all in action in class-fep-group-message.php file. See this file.

You can add following code in your theme’s (child theme’s if you are using) functions.php. It will hide those users from autosuggestion who unchecked “Allow others to send me messages?” in their settings.

add_filter( 'fep_filter_rest_users_args', function( $args, $for, $q, $x ) {
	$args['meta_query'] = [
		'relation' => 'OR',
		[
			'key' => 'FEP_user_options',
			'value' =>  's:14:"allow_messages";s:1:"1";',
			'compare' => 'LIKE',
		],
		[
			'key' => 'FEP_user_options',
			'compare' => 'NOT EXISTS',
		]
	];
	return $args;
}, 10, 4 );

To remove toggle feature entirely you can add following code in your theme’s (child theme’s if you are using) functions.php

add_filter( 'fep_filter_message_toggle_feature', '__return_false' );

If you find any plugin which working with that form, please let me know so that we can try to implement that in our plugin.

Also most hosting support one click staging site creation, you can contact your host if they support that.

If not you can give me access to your website so that i can try to find out where the issue is.

Registration page captcha keys are not coming from this plugin, so it doesn’t matter how many times you change code in this plugins settings page. We need to find out from where this captcha keys coming from. Can you search in db if i tell you what to search?
