This is due to SV - Multi Prefix, please check if you have the latest version
Edit: Otherwise disable Multi Prefix and try install again, after succesfull install enable multi prefix again.
The problem is that probably Multi Prefix don't like Resources Layout, as Multi Prefix also works on resources.i know there is an newer version from XFRM Resources Layout. The newest version is 2.2.0
But i dont have acces to this at this time. Why does multi prefixes made problems with XFRM Ressources Layout Addon?
I dont get this.. But if i delete multi prefix addon and install it again i need to rebuild all the custom work :/
