title: magento 1.9.3.7 You did not sign in correctly or your account is temporarily disabled
body: <p>I just upgrade from Magento 1.9.3.3 (form key disabled) to 1.9.3.7. Now I cannot login to the backend. The error message is 'You did not sign in correctly or your account is temporarily disabled.'</p>
  
  <p>I tried to reset the cookie domain, clear the cache and session from both server and browser and still no luck.</p>
  
  <p>There are many posts concerning magento 2, but far less talking about magento 1. Does someone with magento 1 had and solved this issue? Thanks for your help in advance!</p>
