suexec policy error

Yesterday I modified my .htaccess file, attempting to consolidate the www and non-www landing pages of my site, referring all requests to the non-www URL.  Unfortunately, that unexpectedly interfered with my online booking engine, which was configured to load only pages with the www prefix.  I deleted the revised .htaccess, but the online booking engine is stalling over a suexec policy error.  Here is the error log (I don't have access to the suexec log):

[Thu Sep 19 20:10:16 2013] [client] suexec policy violation: see suexec log for more details, referer:
[Thu Sep 19 20:10:16 2013] [client] Premature end of script headers: rsv50std.cgi, referer:
[Thu Sep 19 20:10:16 2013] [debug] mod_deflate.c(615): [client] Zlib: Compressed 636 to 384 : URL /cgi-bin/rsv50std.cgi, referer:

I have set permissions for rsv50std.cgi and booking_data.html to 755, but the issue persists.

Does the scripts folder itself have 755 permission, the file might but if the folder doesn't then the file's will still not be accessible.

Correcting folder permissions, and also a mistake on the first line of some .pl and .cgi files, restored activitiy to the scripts.  Thanks for your input.
