I get the following error in the log: Unable to load lifecycle for Change Management
I assume you edited lifecycles from web UI previously?
In RT 5.0.6, we added lifecycle deletion support, and to allow admins to delete lifecycles from web UI, lifecycles defined in config files are not loaded any more as long as lifecycles are defined in database(i.e. when you edit them from web UI).
For now, you can revert this patch:
https://github.com/bestpractical/rt/commit/ce3adb04c2d0e82ecd66d0ed4445caa4f356e7d8.patch
Note that with this change, you won’t be able to delete lifecycles defined in config files from web UI.
We are working on a better fix for this. sorry for the inconvenience.
