[xwiki-users] Anonymous users with administrative rights

Hi, I'm doing tests with the 7.4.4 version, using the skin colibri. When I give right of access "program" to non-registered users, they gain the ability to manage the XWiki, anonymously. I gave this kind of access that is occurring parsing error when I use the skin colibri. Codes velocity, for example, in XWiki Preferences not work. In other words, there are two problems: anonymous users with the right management and errors in the execution of velocity codes. Log:WARN  org.xwiki.velocity.internal.DefaultVelocityEngine - Deprecated usage of method [com.xpn.xwiki.api.XWiki.parseContent] in 41:/skins/colibri/view.vm@25,47 Thank you in advance,Julio
