Shamim's Plugins

Did you change theme to default theme and tried?

Sorry for the late reply.
Did you follow my last message?

you can use fep_get_new_message_button() and fep_get_new_announcement_number() function.

I actually did not understand your question. You want to change your avatar image?

if your php version 5.3+ add following code in you theme’s (child theme’s if any) functions.php

add_filter( 'fep_filter_display_participants', function(){
	$participants = get_post_meta( get_the_ID(), '_participants' );
	return implode( ', ', $participants );
	
});

this will show user id (as you suggested) in participants list.

Please check now.

Sorry for the inconvenience.
Did you update from any previous version? If yes, from which version?
Please let me know your php, mysql and wordpress version.

Give me admin access of your website and ftp access so that i can try.

Regards
Shamim
