I'm hoping someone can help. A brand new installation of the latest version of Moodle, running a theme I know well (Herald from 3rd wave media). The site is sometimes failing to load the theme (this happens even with the default theme) and in the /theme/ I'm getting files generated which follow this naming convention: core.xxxxx where the xs are numbers. Has anyone seen this before, and if so - do you know what I can do about it, please?
I'm attaching a screenshot of the current directory listing, in case that helps.
Thanks very much in advance.
