[Koha] koha opac error log 2

Good day all! This post is related to my previous post: http://koha.1045719.n5.nabble.com/koha-error-log-td5762696.html Again, this comes up in my opac error log in /var/log/koha/instancename/opac-error-log: opac-suggestions.pl: Use of uninitialized value $borrowernumber in numeric eq (==) This again occupies substantial amount of my meager hard drive space which I have to delete every now and then. What does this mean and how do I prevent it?
