I'm in the development environment and the cache is locked on five minutes. The config settings are correct, and I see nothing obvious in the extensions that would cause a conflict.
This install was also working just fine until it wasn't. I noticed on line 525 of the changelog that a similar issue came up and was fixed by Mr. Long, but that issue describes the behaviour. Any ideas would be greatly appreciated. The extensions are: file_system_resources page_factory page_parts ruby 1.9.2 radiant 1.0.1p180
