CMS Made Simple Forums

I have used CMS Made Simple in the past, but have not actively used it for a few years. A friend's website was not allowing me to connect to the database so I downloaded backup and mysql dump and am attempting to reinstall CMS Made Simple 1.11.5 (what I'm currently running on my site) but keep running into the following error and don't know what is going on or what to do next:

Fatal error: Class 'Smarty_CMS' not found in /home/steff/public_html/lib/classes/class.CmsApp.php on line 394

Any help is greatly appreciated, thank you.

Check (and update) all folder paths in the config.php file
Afterwards clear cache

turned out to be a config.php file issue with old password info.
