How did you install the PIA?
Is the file /var/www/html/cacti/lib/plugins.php present?

What was the output of the patch command? Did you install the pa.sql to the cacti database?
If everything fails, you may delete the cacti installation and re-install the code (do NOT change the existing database!) to start fresh
