Question

change the narration they asked me not to visit that site​

Answer 1

The given sentence is already in the reported/indirect speech. It should be converted into direct speech as shown below:

They said to me, "Don't visit this site."

Explanation

The given direct speech sentence was an imperative sentence.

When we change an imperative direct speech or vice versa into indirect speech we do the following changes:

1. Reporting verb is changed according to the request, advice, suggestion, or command tone of the sentence.

2. Linking word 'to' is used to join the quoted speech with the reporting verb. In case the sentence is negative 'not to' is used.

3. The other changes of the tense, time adverbials, and pronouns are the same.
