I am having problems using the Cache libraries. It appears simple enough in the docs, and I have tested it out using a Core front-end and File back-end without a problem. But when I try to use the Page front-end and File back-end there is no caching. I have tested start() and it is returning false, but there are no errors anywhere. I did have to chmod the cache directory with the Core front-end, File back-end configuration, but I would assume that the changes made there would work on the other config using the Page front-end. Any help out there, I would really appreciate it.

Thanks

I've found that the page frontend will silently fail if none of the 'cache_with_X_variables' are set to true (all are false by default) in the 'default_options' configuration. Without caching with any variables, the page frontend does not automatically generate a page ID, and therefore will always return false...
