Hello A new version of the Limits Application is available. See http://extensions.xwiki.org/xwiki/bin/view/Extension/Limits+Application/#Hv… You can install with the Extension Manager. This version fixes an important bug which prevents the user to install the application via the Extension Manager. However, I would remind you that using the Extension Manager to install this particular application is not the recommend way, since any user having the administration right will be able to uninstall it. And thus remove the limitations you wanted to enforce. Have a good day, -- Guillaume Delhumeau (guillaume.delhumeau(a)xwiki.com) Research & Development Engineer at XWiki SAS Committer on the XWiki.org project
