Using 2.2.0-rc1, I've suddenly started to experience error messages that are printed to the screen instead of being printed to the log file.
E.g. running something like this from my Snippets and plugins is now suddenly appearing on the page and NOT in the logs:
$modx->log(xPDO::LOG_LEVEL_ERROR, 'My error message');
Anyone experience this? Is this a bug? It wasn't doing this before.
