Hi, Deleting the XWiki.Admin user is not a good idea. It is generally used as the last author and content editor of pretty much all the default XWiki documents, most of them containing scripts. A script can only execute if its last content author has the SCRIPT right. If that author is deleted, then the script also loses its right to execute. So it does not matter what user you use to *see* the script, but what user you used to *save* the script (thus granting it the rights of this last user/author). My suggestion is that you undelete/recreate the XWiki.Admin user (easiest option) and then disable it (i.e. mark it as inactive to not allow it to log in), if you don`t want to use it. This way the old scripts inside wiki pages will resume functioning. Note that this is not only about the Admin user, so you need to be aware that once you delete a user, you "revoke" the right of execution for any scripts he might have authored. This is generally a good thing, but it can also bite you, as you`ve seen. This extension might also be useful (but recommended only for users other than XWiki.Admin): http://extensions.xwiki.org/xwiki/bin/view/Extension/Change+Content+Author Hope this helps, Eduard On Tue, Aug 16, 2016 at 11:38 AM, Tom Neumann <tom.neumann(a)outlook.de> wrote:
