What error do you see?

but wp-admin and wp-includes cannot be uploaded in the cpanel.

Why they cannot be loaded?

Useful codex guide: Manual Update

It just says “An unknown error occurred.”

And it also says that max size is 1.5??

And it also says that max size is 1.5??

have you discussed this with your hosting provider?

No, I haven’t. Maximum file size allowed for upload: 1.51 GB
But I should have 4 GB allowed.

So, this might be the problem?

Pose all these questions to your hosting provider. They know their servers better!

Thanks, I will do that! I have no idea what else to do!
