Error Addon, subchunk palette

Appears on the screen a lot of messages of error of an Addon/ subchunk palette.

It's really annoying when I'm playing. Only appears on realms or servers (does not appear on my worlds)

I deleted all the packs of textures that I downloaded but apparently that's not the problem.

 

These are the messages :
