Pink And Black Blocks Issue

Its been a while since I played Minecraft
so I missed wynncraft, and it is the only RPG server/game i can play :(
but when I logged in, the texture just got glitched, i think...
I looked carefully what are these blocks? I figured it was grass! its sreally annoying and I don't know how to fix it, please help me!

 

Are you using forge? If so, that may be the cause of your problem. Uninstall it and see what happens.

 

but i need forge, so i can use xaero's minimap

 

You don't need those filthy minimap mods, I already know every location by heart. You should too!
(unless there's something else you use it for)

 

I only use it to make waypoints for villages, NPC,etc...
but if that's the only way to solve this problem, well, I had no choice :(

 

I'm oretty sure using mods are bannable.

 

Nope, using minimap mods are fine, as long as you don't have the entity radar enabled.

 

entity radar? -I didn't know its illegal-. pffft, no way I don't enable this thing. and what's the point of making entity radar :D
*disconnect WiFi*

 

MC 1.8.9, with Forge for 1.8.9, with your minimap, should work OK. It works for me, and I've even got LiteLoader for 1.8.9 on it.
