Error message when trying to add a redirect

I am trying to redirect a parked domain to another place on my site and receive this error: There was an error adding the redirect. Apache detected an error in the Rewrite config.

Syntax error on line 4 of /home/lighth31/public_html/.htaccess.MRCSXStLeW2sErolCyI85o92iXZrjcBb: Invalid command 'suPHP_ConfigPath', perhaps misspelled or defined by a module not included in the server configuration 

Please try again.
