Shamim's Plugins

Which version you are using?
Did it worked before?
Do you have any custom code for this plugin?
Can you change “Who can send replies”?

License can be used in development website as long as your development website url subdomain is staging or dev OR tld is dev or local or test.

Eg. if your main website domain is example.com then development website url should be
staging.example.com
dev.example.com
example.local

etc

Use like

add_action( 'transition_post_status', function( $new_status, $old_status, $post ) {
    if ( 'fep_announcement' != $post->post_type ) {
	return;
    }
    update_post_meta( $post->ID, '_fep_email_sent', time() );
}, 10, 3 );

It is always recommended to use latest version. If possible, update to latest version.

In your version, you can use add_meta_box to show checkbox in announcement add page.

to prevent email sending you can use update_post_meta( $message_id, '_fep_email_sent', time() ); in your save function.

Again, if possible, update to latest version so that you can easily achieve this. I can provide you full code if require for latest version.

I am really sorry for issue arise. In this major version plugin performance is highly improved. So some of the function could not be backward compatible.

To see full changes of this plugin please see https://github.com/shamim2883/front-end-pm

add_action( 'gfpdf_post_save_pdf_5', function( $pdf_path, $filename, $settings, $entry, $form ) {
		global $wpdb;
		$user = wp_get_current_user();
		$user_ID = $user->ID;	
		$message = array(
			'message_title' => $form['title'],
			'message_content' => "Message Goes Here",
			'message_to_id' => $user_ID,	
		);
		$override = array(
			'post_author' => 1,
		);
		//Turn off email send
		remove_action( 'fep_status_to_publish', array( Fep_Emails::init(), 'send_email'), 99, 2 );
		//Post message in Frontend PM
		$message_id = fep_send_message( $message, $override );
		//Prepare Attachment
		$upload_dir = wp_upload_dir();
		$upload_dir = $upload_dir['basedir'];	
		$subdir = '';
		if ( get_option( 'uploads_use_yearmonth_folders' ) ) {
				$time = current_time( 'mysql' );
			$y = substr( $time, 0, 4 );
			$m = substr( $time, 5, 2 );
			$subdir = "/$y/$m";    
		}
		$upsub	= '/front-end-pm' . $subdir;
		$copy_to_dir = $upload_dir . $upsub . '/';
		if( ! is_dir( $copy_to_dir ) ) {
			wp_mkdir_p( $copy_to_dir );
		}	
		$newfilename = wp_unique_filename( $upload_dir, $filename );
		$pathtofile = $copy_to_dir . $newfilename;
		copy( $pdf_path, $pathtofile );	
		$attachment[] = array(
		 'att_file' => $pathtofile,
		 'att_mime' => 'application/pdf',
		);
		//Add attachment to Frontend PM post
                FEP_Attachments::init()->insert( $message_id, $attachment );
		//Update user information
		update_user_meta( $user_ID, 'payment', '' );
		update_user_meta( $user_ID, 'renew', date("Y-m-d", time()));
	}, 10, 5 );

I have corrected above code (untested), Please check.

For query messages new class FEP_Message_Query added. Please use this class. You can go to class-fep-messages.php and see user_messages method to see how it is used. You can also see FEP_Message_Query class __construct to see what args you can pass.

Let me know if any more assistance needed.

You can download latest version from https://www.shamimsplugins.com/checkout/purchase-history/

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

If still not working let me know.

You can add a link like <a href="http://example.com/index.php?your_action=delete&id=1">Delete</a>. Then in init hook use that function to delete that message. Check permission and nonce first if that user have permission to do so.
