Redmine

Hi!
The plugin redmine_knowledgebase, version 3.2.0 causes an error/crash in Redmine 3.2.

After installation of the above plugin, you can not use the GLOBAL SEARCH (upper right corner of the main-menue) function in Redmine. If you enter an unknown ticket number or any other string, you'll get an error.

The system crashes with this internal error:
