Hi All, I am tryiing to install BulletinBoard Application in xwiki.I followed the installation procedure. # Step 2 : Tell the wiki where to find the right languages resources. * In the administration menu, click on the "Preferences" tab. * Click on the "Advanced" sub-menu. * Scroll in this menu until you can see "Internationalization Document Bundles:" written. * In that field, copy-paste the following text : "BBCode.Translations," * Save the page. The problem here is I am not atall getting a preference Tab and Advanced submenu.Thats why I am getting the text like bb_bbcodespace # b_createnewbbs bb_adminbb # bb_changelookbbs bb_skinbbs # bb_changetranslationsbb bb_translationsbb # bb_apanelisavailable bb_bbpanel. bb_usepanelwizard bb_gotopanelwizard? Also If I am trying to add a new topic by going to bb_category : CategoryClassTemplate I am not able to save that.I am encountering with the following error java.lang.NullPointerException at
