So here is the deal. I updated all plugins, minus the ones that did not have updates. Ran a test server for compatibility, then went live with the plugins. My first bug is that mirroring for groupmanager doesn't seem to be working. My code is as follows: CURRENT PASTEBIN Code: TEST: TEST_nether: - users - groups Spawn: - users - groups Minecraftia: - users - groups Creative: - users This worked with 1.4.6 with no issues. Now that I updated, a user promoted in one world doesn't seem to have their promotion follow them in another. Ie: User is promoted in the SPAWN world and when they do /spawn, they are not that rank anymore. EDIT 1: Changed the code to the following, now i have an interesting error: Code: TEST: - TEST_nether - Spawn: - Minecraftia: TEST: Creative: - users also went back to the above, and i get this in the console: Code: 2013-04-14 21:49:06 [INFO] GroupManager version 2.0 (2.10.1) (Phoenix) is disabled! 2013-04-14 21:49:06 [SEVERE] GroupManager - SEVERE - There are errors in your config.yml. Using default settings 2013-04-14 21:49:06 [INFO] GroupManager version 2.0 (2.10.1) (Phoenix) is enabled! however, after reading the config.yml i see no errors. i even generated a new file and updated the mirroring section. EDIT 2: Fixed the issue, apparently GM changed its config.yml file. After regenerating a new one and adding the proper mirrors, all was fixed.
