i don't know why to go there
这句话哪里有错啊?

i don't know why to go there这句话哪里有错啊?
1L是一种改法,意思是"我不知道怎么去那里"
如果你要的意思是"我不知道为什么要去那里"
应改成i dont know why i go there
WHY在这里引导宾语从句 ,含TO不定式只是一个短语,不是完整句子

不要to

I don't know why go there.

KNOW后边少一个主语

i don't know why I go there

不要TO
i don't know why go there

why，应用how

你的意思是说：我不知道我为什么去那里？是吗？是的话。要这样改
I do not know that why i go there

这是一个宾语从句补全为
I don't know that why I need to go there.
显然，你的句子中宾语从句里缺少主语

句法错误。
正解如下
I have no idea why I went there
