When you intend Hubzilla specific codes with [observer=1][/observer] to parsed, then caused those string [observer=1][observer.baseurl]/settings/features[/observer] -> Additional Features ohne wrong URL with attached additional false characters. Only with one line break is the result OK. For comparsioin:
[observer=1][observer.baseurl]/settings/features[/observer][/nobb]
-> Additional Features For example Searchquery limited for searchresults from your favoured channel . A Bugreport wrong parsing for string [observer.baseurl] /settings/features is created.
