So that's the configuration you used for your site?

Uhm, no. The StringFrontend is made for storing strings, not variables,
thus no arrays can be stored.

But TYPO3 stores the cached data as an array:

if (TYPO3_UseCachingFramework) {
	$cacheData = array(
...
$this->pageCache->set(
	$this->newHash,
	$cacheData,
...

So yes, you cannot use the StringFrontend for the "standard" TYPO3
caches, but besides that it works perfectly for other cases. :)
