Access denied; you need the SUPER privilege for this operation - MySQL
<p>I have my user <code>root</code> with all privileges on, I checked over and over and still show the same error, but wheren I try to change the value of the variable <code>max_user_connections</code> FROM <code>phpmyadmin</code> it display this error, in the plesk interface (I'm running a Windows server) where the list of user appear all the privileges of my user is enabled so I do not why this error.</p>

<p>But I ran this queries in <code>phpmyadmin</code></p>

<p><code>SHOW GRANTS;</code></p>

<p><code>SELECT USER();</code></p>

<p><a href="https://i.stack.imgur.com/HFnY1.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/HFnY1.png" alt="enter image description here"></a></p>

<p><code>SELECT CURRENT_USER();</code></p>

<p>I get <code>root@%</code></p>

<p><strong>(Sorry but Stackoverflow says that I can't post images because of my reputation and no more than two links)</strong></p>

<p>There is a difference between <code>root@localhost</code> and <code>root@%</code>?</p>

<p>And why in the first image the first line says <code>GRANT USAGE ON...</code>?</p>

<p>How I can give the <code>SUPER</code> privileges the user needs? thanks.</p>
