"Pro" appearing in my page before the output of body content

I try to check if I put that word in my source code but I didn’t. Thinking that the error is with my browser I change I try with another browser but still the word is there.

I created another simple html page in other project and tried to load it in the browser that "Pro" was not on the page loaded. I tried also to see the source code of my page in the web browser I see the word is before <!DOCTYPE HTML>


Pro<!DOCTYPE HTML>

It was in a file where I couldn’t imagine it to be. config/web.php before any


<?php

.

Don’t use the forum for idle chatter, please.

It’s just wasting our time.
