A few errors were listed when i went to Joomla-SMF Forum -> about page

First, here's what i am using:

Joomla version : 1.0.13 Stable
SMF version : 1.1.2
Joomla-SMF version : 2.0.2.1

my website: www.emergenetwork.org/home

The error messages:

Warning: fopen() [function.fopen]: URL file-access is disabled in the server configuration in /home/emergene/public_html/home/administrator/components/com_smf/admin.smf.class.php on line 2041

Warning: fopen(http://www.joomlahacks.com/news/mh_mambo_smf_help.rdf) [function.fopen]: failed to open stream: no suitable wrapper could be found in /home/emergene/public_html/home/administrator/components/com_smf/admin.smf.class.php on line 2041

Warning: fclose(): supplied argument is not a valid stream resource in /home/emergene/public_html/home/administrator/components/com_smf/admin.smf.class.php on line 2043

Would anyone have an idea how i may address these errors?

Many thanks,
