Basically this is because of the SQL state 4000 error which is also called as SQL deadlock error. While I try to fix this issue, I would like to see if there is a way to change the text of this error --</p>
  
  <p><strong>"The Website encountered an unexpected error. Please try again later" .</strong></p>
