Cosmiqum is small and fast CMF that is aimed to make any site quickly. Almost all of its functionality is implemented through plugins. Any plugin can register a filter for a specific event and any plugin can be a filter, which is useful for plugins that need to process another plugin's data. Every action in the core is logged and any plugin can log any of its actions. PHP errors are not displayed to the user, but the developer can get them from a specific array. Different configurations can be used for different hosts.
