Summary of Changes

Gracefully handle cache related errors in com_cache versus hitting the error page.

Catch some exceptions when trying to read data from the cache store and display a relevant message related to the failure.

Clean and purge operations should also catch these exceptions to notify the calling code of an error state. The controller methods are already checking for boolean false returns so the error handling already exists.

Remove a useless casting from boolean to integer.

Testing Instructions

When the cache can't be reached for read, clean, or purge operations, the error conditions should be gracefully handled versus fatal errors.
