My log files are big. Yesterday’s was 65mb. The majority are this: [2015-10-27 15:34:57] mautic.CRITICAL: Uncaught PHP Exception LogicException: “The controller must return a response (null given).

Mautic 1.2.2 should fix those errors. It was released yesterday. Could you tell us if it got better after update? ---

I updated and didn’t see any immediate change, then went in and deleted all the cache files (you know it would be nice in the settings to have a button that flushed the cache for you), that seems to have slowed the messages down considerably. I will keep an eye on it today. ---

I have run 1.2.2 with the cache cleared for about 20 minutes now and no new errors have hit the log, previously I was getting at least 1 per second. I would say that it is resolved. ---

Great to hear that. The button for clearing the cache is a good idea. It might get lost from the sight of developers. If you report it to [https://github.com/mautic/mautic/issues](https://github.com/mautic/mautic/issues), it won’t get lost. ---
