Shamim's Plugins

Please add following code in your theme’s (chilld theme’s if you are using) functions.php

add_filter( 'fep_eb_email_legends', function( $legends, $mgs ){
	$legends['sender_username'] = array(
		'description'  => __('Sender Username', 'front-end-pm'),
		'where'        => array( 'newmessage', 'reply' ),
		'replace_with' => ! empty( $mgs->mgs_author ) ? fep_get_userdata( $mgs->mgs_author, 'user_login', 'id' ) : '',
	);
	return $legends;
}, 10, 2);

If you use “v2 invisible” captcha then you can set to show on left. See settings page of this plugin.

If you use v3 then google currently not allow any settings to position on left. But you can hide and add your own instead. Please see https://developers.google.com/recaptcha/docs/faq#id-like-to-hide-the-recaptcha-badge-what-is-allowed

I cannot access some of pages of your website, Always timeout.
If you can you can send me screenshot so that i can see.
Please go to https://www.shamimsplugins.com/live-chat/ and start chat (this link will be available for next 30 minutes)

It seems you are using GoDaddy hosting, they have build in caching. You can ask them to exclude message page if possible. otherwise your users will see messages couple of seconds later.

Is your email issue for announcements solved now?

Please check now.

Also disable message page caching. Otherwise your user will not get message immediately when send.
This plugin already have build-in caching.

Please let me know following.
1. Are you using this plugin (FREE or PRO) from before?
2. Do you have messages from previous version?
3. Check database and see if there any database table name start with PREFIX_fep_ where PREFIX if your database table prefix. if yes, let me know how many and what are they.
4. Do your set database user in wp-config.php have permission to create database table?

To reverse add following code in your child theme’s functions.php

add_filter( 'fep_filter_get_message_with_replies', function( $args ){
    $args['order'] = 'DESC';
    return $args;
});

To show reply form at top you will need to override view-message.php template. Instruction in https://www.shamimsplugins.com/docs/front-end-pm/customization/change-templates-2/

OR you can add a button to jump to reply form. add <a href="#fep-content-single-reply-form">Reply</a> where you want to show that button.

Thank you. Glad it solve your issue.
I have found a topic in your mentioned plugin which explain it. It is for Contact form 7 but may be same issue here. https://wordpress.org/support/topic/conflict-with-contact-form-7-4/#post-9535815 . You can try same solution if your want. (instead of “contact-form-7” use “front-end-pm” in the url)
