[xwiki-users] Failed to execute the [velocity] macro. Cause: [The execution of the [velocity] script macro is not allowed...

Thanks Thomas, my previous issue was a problem when I imported the db to the new server. After the migration, I got this error. 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. I searched but I cant find where to set right for the velocity macro. Can you help me a bit please ? Sébastien
