Shamim's Plugins

Glad it worked. CF7 changes too much and sometimes it is impossible to get the code right for them. This is one of the case.
I worked with that plugin developer and solved this issue about 2 years ago. Now that code is again changed. See https://wordpress.org/support/topic/is_user_logged_in-always-return-false-inside-wpcf7_before_send_mail/

I will try to solve the issue again in the core.

Did you tried with only domain (without http part)?
If still not possible please give me live site access using https://www.shamimsplugins.com/sensitive-information/
Also let me know if captcha is working for other forms? Eg. login, register?

Please follow https://www.shamimsplugins.com/docs/front-end-pm-pro/troubleshoot/license-keys-not-activating/

Can you please install the plugin and add your google keys, but do not check any forms in “Enabled Forms”?
Then let me know.
Also let me know if captcha is working for other forms? Eg. login, register?

1. Which version of captcha you are using?
2. Can you recheck your google keys are correct and your domain is set in google recaptcha admin under same keys? (important)
3. Can you send me your website url?

May be in old database there was no custom css. This plugin store its settings in wp_options table. So if that option is present it should take from there.

You can check your old database options table and see if FEP_admin_options option is there. You can also copy that and paste in new database.

I may not get your question properly. If you want to hide your reply, then why you will reply in first place? May you please elaborate your question a little so that i can better answer you if my above answer is wrong?

As this plugin support multiple recipients, showing other users name is little confusing as there may have more than one receiver. If you support to send message to only one receiver then you can follow following approach.

If you want to show other users avatar add following code in your theme’s (child theme you are using one) functions.php

add_filter( 'fep_remove_own_avatar_from_messagebox', '__return_true' );

If you want to show other user name add following code in your theme’s (child theme you are using one) functions.php

add_action( 'fep_message_table_column_content_author', function(){
	$participants = fep_get_participants( fep_get_the_id() );
	foreach( $participants as $participant ) {
		if ( get_current_user_id() != $participant ) {
			?><span class="fep-message-author"><?php echo fep_user_name( $participant ); ?></span><span class="fep-message-date"><?php echo fep_get_the_date( 'mgs_last_reply_time' ); ?></span><?php
			break;
		}
	}
});
