English question, do the following two sentences have the same meaning or one of them is wrong?

I'll try to explain.
In your sentence, the words you need to pay attention to are 'you're feeling'. So when you add a comparison, such as 'than ...' it has to relate to the 'you're feeling'. In that first sentence, the word 'feel' is understood although omitted.

The first sentence is right.
1. I hope that YOU'RE FEELING much better today than YOU DID (FEEL) yesterday.

If you want to use 'you were', the first part of the sentence has to relate, so you could do this -
2. I hope that YOU ARE (or YOU'RE) much better today than YOU WERE yesterday.

Alternatively, you could say,
I hope that YOU FEEL much better today than YOU FELT (or DID) yesterday.

In everyday English? These would both be acceptable. No one is going to even catch it.

Now if you're trying to learn English and taking tests, I don't want to give you the wrong answer. However in everyday conversations no one cares.

The first is better.
Emit "feeling" from the second and it will make better sense.

1 is best.

Did. U would use to be if the sentence was i hope u re better today than u were yesterday. I could explain u why but i hate typing on ipad - get too many typos

How do I find my language setting

No.1 is the normal way in Britain.
