Forum application issue

Hello,

I need help with the forum app. After installing it, creating a topic and adding a reply under the thread, I get an error.

#wysiwyg_import(false) #wysiwyg_storeConfig($parameters $myeditor.get('doc') $myeditor2 false) #wysiwyg_writeConfig($jsVarName $parameters)

also, after adding comment, in the place where should be author i have:

PNG?CACHE-VERSION=1708942723000" ALT="TESTUSER" /><A CLASS="USER-NAME" HREF="/BIN/VIEW/XWIKI/TESTUSER">TESTUSER</A></LI></UL> {{/HTML}} 

How to solve it?
