New subject: [xwiki-users] failed to execute velocity macros

16 Aug 2016

Hi, Tom,

Depends how you`ve deleted the Admin user.

If you`ve just sent it to the recycle bin, then going on the
http://<server>/xwiki/bin/view/XWiki/Admin
page should show you the option to restore the profile page from recycle
bin.

If no such option exists (and you`ve deleted it from the recycle bin as
well), the you have to recreate it. Just go to the same page, press the +
(create page) button, make sure "Terminal page" is checked and hit
"create", then "save". After that, go into object edit mode on the
same
page and add an object of the class XWiki.XWikiUser. Hit "Save" and the go
into view mode where it should start looking like a user profile page
again. The next thing would be to reset its password so that you can then
log in with it at some point.

Another option (instead of recreating it) would be to completely restore it
by manually re-import just the XWiki.Admin page from the UI XAR, but I
would need to know what exact XWiki version you have so I can give you the
right link.

Thanks,
Eduard

  Hi Eduard,

 thanks for your help!
 How can I recreate the user if the macros don't work at that point?
 It does not seem to work out.

 Thanks,
 Tom

 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

 After that I logged in with the LDAP user and deleted the old admin
 account and tried to set my LDAP user as owner of the wiki.

 Now every page shows this message:
 Failed
  to execute the [velocity] macro. Cause: [The execution of the
 [velocity] script macro is not allowed. Check the rights of its last
 author or the parameters if it's rendered from another script.]. Click
 on this message for details.

 Even the superuser account can't see the pages normally.
 What can I do? Is there a setting to give velocity macro rights to
 everybody?
 Or can I edit the database somehow?...

 Thanks,
 Tom
