Somewhat weird problem with GL shader compiler

Recommended Posts

I verified that both the vertex and fragment shader in the program are functioning but glGetUniformLocation is still returning -1 for uniform variables that were working 10 minutes ago. I don't think I altered any related code and there are no compile or link errors.
uniform vec3 LightPosition;//vertex header
int pnt = glGetUniformLocation(shaderProgram[0], "LightPosition");//source
Pretty straight forward I think.
