When launching MySQL, I get the following InnoDB errors.

mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql

It won't start because you changed the size of your innodb log file size (or in this case; you commented it and MySQL is using the default now).

log file ./ib_logfile0 is of different size 0 503316480 bytes
InnoDB: than specified in the .cnf file 0 5242880 bytes!

If you have data in your MySQL database, I suggest you put back the innodb log file size value to its original value by removing the hash mark:

innodb_log_file_size=503316480

Also, if you're really interested in changing this setting; know that it is tricky as you might lose data in the end. If you really need to change this setting, follow this guide on MySQL.com: http://dev.mysql.com/doc/refman/5.1/en/innodb-data-log-reconfiguration.html
