util.pubsub: Ensure deleted node stays in memory store deletion failed This looks like a copy/paste fail. The in-memory representation could get out of sync if the storage failed to delete the node (it would report an error, but would no longer be listed until a server restart re-read it from storage).

module:log("error", "mod_pep_plus has been renamed to mod_pep, please update your config file. Auto-loading mod_pep...");
module:depends("pep");
