Have you tried switching off your plugins from other sources yet? You have plugins from lots of different sources and that usually causes problems.

Try loading it up again with only Yanfly plugins enabled, and see if you still get the error. If you don't get the error after switching off plugins, there's a problem with plugin compatibility. You can turn on the other plugins one by one to figure out which one is causing it.
