Material doesn't have a color property '_Color'

I have been following a tutorial on how to code shaders and I have run into an odd problem which the Tutorial poster does not have, even though I checked for typos about 10 times and m eyes are starting to hurt. Could anyone look at my code and check if they can find what i did wrong ?

 Shader "Shaders/2 - Lambert" { //Shader Path
     Properties { //Define any changeable properties here
         _Color ("color", Color) = (1.0,1.0,1.0,1.0) //Color property 
     }
     SubShader { //Main Shader
         Pass {
             Tags { "LighMode" = "ForwardBase" }
             CGPROGRAM
             //pragmas
             #pragma vertex vert
             #pragma fragment frag
             
             //User defined variables
             uniform float4 _Color;
             
             //Unity defined variables
             uniform float4 _LightColor0;
             
             //Base input structs
             struct vertexInput{
                 float4 vertex : POSITION;
                 float3 normal : NORMAL;
             };
             struct vertexOutput{
                 float4 pos : SV_POSITION;
                 float4 col : COLOR;
             };
             
             //vertex function
             vertexOutput vert(vertexInput v){
                 vertexOutput o;
                 
                     float3 normalDirection = normalize( mul( float4( v.normal, 0.0 ), _World2Object ).xyz );
                     float3 lightDirection;
                     float atten = 1.0;
                     
                     lightDirection = normalize( _WorldSpaceLightPos0.xyz );
                     
                     float3 diffuseReflection = atten * _LightColor0.xyz * max( 0.0, dot(normalDirection, lightDirection) );
                     
                     o.col = float4(diffuseReflection, 1.0);
                     o.pos = mul(UNITY_MATRIX_MVP, v.vertex);
                 return o;
             }
             
             //fragment function
             float4 frag(vertexOutput i) : COLOR
             {
                 return i.col;
             }
                 
             ENDCG
         }
     }
     //loads Diffuse in case the Shader doesn't get loaded
     //Fallback "Diffuse"
 }

Thanks in advance

Edit: exact error message: Material doesn't have a color property '_Color' UnityEditor.HostView:OnGUI()

Edit: for some reason getting another error message now: rc.right != m_GfxWindow->GetWidth() || rc.bottom != m_GfxWindow->GetHeight()
