  <p>I searched some answers but I couldn't solve my problem. </p>
  
  <p>I don't know if I gave all the information that you need, so if you need something else, just tell me. I have a database connection from different computers and I had a user created to access the database but it had <code>%</code> in the hosts row, so I wanted to change it with an IP address for security issues and it gave me this error so now I'm stuck. </p>
