Dont worry then, im not going to write out a whole essay just for you to tell me to remove all my plugins one by one :L I just thought someone might know what that error message means :/

 

Well that's kinda need to know information to accurately address a problem...

 

Well you wouldnt have answered in time anyway if you are replying to this now and second unless you know what that error message means you wouldnt have been able to tell me how to fix it.

 

The error message means, stop using R6 and USE 1.2.3 R0.2!

 

Infact it does not.
