 basics.php function clearCache()
 On some PHP versions like 5.2.5
 glob returns FALSE for empty directory, so clearCache throws warnings in
 foreach loops.

 It can be fixed ba casting to an array like:
 ...(array) glob($cache)...
 or by checking with is_array().

 Also this issue is documented here http://bugs.php.net/bug.php?id=43407,
