Shamim's Plugins

Keys are coming from settings page of this plugin. It is in Dashboard > Settings > Advanced noCaptcha & Invisible Captcha > Google Keys

Also check is there any other plugin which support captcha and keys are coming from there.

You can add like <a href="{{announcement_url}}">YOUR TEXT HERE</a>.
Change YOUR TEXT HERE to whatever you like.

Which version of captcha you ate using (v2 or v3)?
Can you give me your that page url so that i can check?

It seems you are using v3 which does not have any user option to validate.
Also you are using multiple captcha source (this plugin and divi) in the same page which breaks the captcha.
Please use only one (this plugin or divi) captcha source.
Also if possible use v2 which have user option to validate captcha.

Which key? Google key or license key? If google key then create new one if that fix the issue. If license key then follow https://www.shamimsplugins.com/docs/advanced-nocaptcha-recaptcha/troubleshoot-2/license-keys-not-activating-2/

Date under name should be last reply time. But it updated when next time visit the page after send a reply.
Date format come from your settings in Dashboard > Settings > General.
If you want to show “x ago” Then add following code in your theme’s (child theme’s if you are using) functions.php

add_filter( 'fep_formate_date', function( $h_time, $date ){
    return sprintf( __( '%s ago', 'front-end-pm' ), human_time_diff( strtotime( $date ) ) );
}, 10, 2);

Thank you again.
It seems some of your htaccess rules preventing to send cookie which breaks wp rest api.
Your SFTP credentials is not working for me so that i could not see your htaccess file to get the exact problem. You can remove all other rules except wp default rules from your htaccess then test.

Let me know.
