HL2RP Constantly getting this console error

Sorry if I seem to be posting a lot, I'm just trying to fix everything and get everything right before the server's launch. For some reason, when I do certain things like buy from a salesman or add/remove text, I constantly get this error no matter what I do

Spoiler

[ERROR] gamemodes/clockwork/framework/sh_kernel.lua:3848: attempt to call method 'gsub' (a nil value)
1. Replace - gamemodes/clockwork/framework/sh_kernel.lua:3848
2. Decode - gamemodes/clockwork/framework/libraries/client/cl_chatbox.lua:460
3. unknown - gamemodes/clockwork/framework/libraries/client/cl_chatbox.lua:1245
4. func - gamemodes/clockwork/framework/libraries/sh_datastream.lua:160
5. unknown - lua/includes/extensions/net.lua:32

I tried searching the error but no one seems to have the sh_kernel.lua error, they have something else. Anyone know what to do about this? Thanks

 

Did you mess with the core schema files?
What plugins do you have installed?

 

I have a lot but it's been there since I replaced the beta version with the stable version of the schema. It may be that some files are still beta version which produces the error. I replaced the gamemode files with the stable so I'm not sure why the error would be coming from there if it was from the beta version
EDIT: reinstalled clockwork and everything fixed
