Hi everyone! New here, and loving Atahualpa! I've only been running it for a while, but today I got an error message about a sbm-stub.php in an app folder path was deactivated due to invalid path. However, I don't know what that path was, or could have been, because there is no app folder installed with 333. But after that warning, I can no longer submit changes to any of the theme settings. They just won't apply.
