saving and loading files - returns blank documents -

[richardm]

Problem

I used the add file function within a page to save a document.  When retrieving using the created link, a blank document is received (zero length file).  I tracked the problem down to Class-knowledgeroot-header.php 418 where it does the unserialise(...) of the document which was returning FALSE. 

Solution
After some searching I found a page http://davidwalsh.name/php-serialize-unserialize-issues which documents a bug and recommends the use of base 64 encode and decode.  Implementing this in  Class-knowledgeroot-header.php for the load and save seems to cure the problem

configuration
I'm using Knowledgeroot (and MySQL) version 0.9.9 on SUSE 10.3 with no updates to PHP or MYSQL
