Server :: Apache2 SVN Post-commit Script Certificate Error Post-commit Hook Failed (exit Code 1) With Output?

I am using apache2 with subversion and trying to get post commit script to run an svn update command. All svn commands seem to work fine manually

Everything used to work fine but then the server ip changed and I can no longer access it with the web name and have to use the ip directly

I am using tortoise svn with vista on my work machine

Here is the script

#!/bin/sh
export LC_CTYPE=en_US.UTF-8
/usr/bin/svn update /home/common/webroot/bob

Here is the result.

Command: Commit
Modified: C:UsersMattDesktopcheckout - bobindex.php
Sending content: C:UsersMattDesktopcheckout - bobindex.php
Completed: At revision: 63
Error: post-commit hook failed (exit code 1) with output:
code....

I think what i need to do is update the certifcate for the apache2, but I'm not sure how to do this, where to put it, and then which of the thousand apache config lines needs to be changed
