Hello, Can you share your log file please ( (https://wrobot.eu/forums/topic/1779-how-to-post-your-log-file-with-your-topic/ ).
(check if your plugins and fightclass are updated)
Hello, in advanced general settings you can use option "Ignore fights when traveling" (you can also https://wrobot.eu/forums/topic/2681-snippets-codes-for-quest-profiles/?do=findComment&comment=13088 but I don't recommand it)
Even in official server this config will cause problems (and I don't speak about usage of plugin like ClearBlacklist.cs in quester mode).
To be sure, if you can try to download another wow client (in another website)
