You might want to find some other RTB replacement or remove it all together. The "CRC list" (a list of add-ons that are specifically banned by Badspot for many possible reasons) isn't liking what you have.

Client checking Add-On: Map_AdjustablePlate
Add-On is in the list of known bad add-on names - will not execute
Maps are no longer supported. You should probably delete those.
Client checking Add-On: Client_AdminGUIPlusOLD
Add-On has been renamed from "Client_AdminGUIPlus" to "client_adminguiplusold" - will not execute
Either you got this add-on from some idiot who decided renaming it works or from a creator who has no idea what he's doing. Consider getting rid of it.
None of these are actually the problem, just simply some things you should do.
Also, you should probably just clean out your add-ons list completely. YIKES!
