[xwiki-users] Right problem with a Groovy macro in a farm

Sorry for this newbie question. I use a XWIKI 2.7.0 farm. I try to use a wiki macro written in Groovy. I saved it with the Admin account in the main wiki. The macro is defined global (in the WikiMacroClass). All works fine in the main wiki. But in the subwikis, even connected as the admin of the farm, I can't execute the macro (even if I see it in the wysiwyg editor). The error message is: org.xwiki.rendering.macro.MacroExecutionException: You don't have the right to execute this script Is there something to do in the Programming panel of the administration page ? Do I have to import the macro in the subwiki ? I started to read that thread http://markmail.org/thread/2i7nkhiugv4z3ara but it didn't help me. Thanks for your help. Maxime Sinclair
