RussellK,
Please don't get confused with scripts.
lt.cgi = This is the main script
lt_reset.cgi = This should only be used to reset latest_threads cache files. This file should never be used to run lt.cgi.
public_lt.pl = This is a custom display option file and you must upload this to your /noncgi dir/Templates/ or you may run into problems.
All the other files are optional.
Remeber to modify the ubb_posting.cgi like the install says or else your lt.cgi will never update.
Keep in mind that you need to post topics so that you can get latest_threads to start building your thread listings.
I'll look at your site soon.
Thanks
