CaRP : Caching RSS Parser : Error : Plugin not found

CaRP: Caching RSS Parser - Documentation

You've called CarpLoadPlugin, but the plugin you named wasn't found.

The plugin name is misspelled: Be sure that you've typed the plugin name correctly (including upper and lower case).
You didn't include ".php" in the plugin name: Be sure that your call to CarpLoadPlugin looks like this: CarpLoadPlugin('flexformat.php');, and not this: CarpLoadPlugin('flexformat');.
The plugin is not installed, or is installed somewhere other than in CaRP's plugins folder: Verify that the plugin has been uploaded to the "plugins" folder inside the "carp" folder (the folder that contains carp.php).
