configuration.php >>>The routing wrapper is not present in this MASTER configuration file.

The above message shown after I checked patches in my slave site. I installed patches several times but the problem still and it caused I can not preview the site that I am editing.

I checked patches in the master site and there was no any error. It happened only in the slave site.

Please help!

Thank you very much.

JMS should never be installed in a slave site.
This is normal that you have such error message because when JMS is installed in the slave site, it detect that the slave site does not contain the stuff to convert in master.

Uninstall JMS in the slave site.
It is not designed to use JMS from a slave site.

If you review the tutorial video you will never see that we install JMS in a slave site.
See for example the video 0.d overview
