This text is generated by the invite anyone plugin
1. The text is crowded. We need to fix that
2. The links don't work as desired

We tired to change wp-content/plugins/invite-anyone/by-email/by-email.php
file, under lines 987.

$inviter_url = bp_loggedin_user_domain();

to

$inviter_url = 'https://www.site.com/ash/membership-account/profile/?pu='.$inviter_name;

but that did not worked on our site.

More details if necessary are available on the live chat transcript.
