Which error is reported depends on which driver you're using and could change from driver to driver. One error could be emitted for many different reasons. The reason for error that you deleted is still a valid one I would think. I suggest you keep that one instead of deleting it, and show both reasons.

the original one is GL_INVALID_ENUM is generated if renderbuffertarget is not GL_RENDERBUFFER., which renderbuffertarget is none of the parameters from glFramebufferTexture2D, maybe it was just a typo or something? lol

Ah gotcha. Looks good then! Thanks :)
