We've recently upgraded to Moodle 2.7 and are using the More theme. We've found the load on our Apache web server has increased exponentially since this upgrade. In watching the processes, it seems to be consistently re-loading theme images and theme related files. We have confirmed we do not have theme designer mode enabled.
Is it possible the theme cache is not working by default in Moodle 2.7? Is there a setting that needs to be enabled? Is it possible this is a bug?
Any insights would be helpful. Right now our server is running dangerously close to the failure point.
