Hi,

I noticed high memory usage and errors recorded every second in my server Log file. How can I solve the errors:

[Wed Apr 01 15:28:33 2009] [error] [client 84.235.75.7] PHP Warning: explode() [<a href='function.explode'>function.explode</a>]: Empty delimiter in /home/*****/public_html/links/lib/category.class.php on line 708, referer: http://www.*****.com/links/index.php
