How to solve error "422:invalid authentication token" in Redmine
<p>In redmine I am getting <em>422:invalid authentication token</em> and the logged in name is displayed with other user name instead of login user. There are no steps to reproduce. All of a sudden it occurs and it will be proper when I refresh the link. Please find the attached image for clear scenario.
In the attached screenshot login user name is Pavithra but all of a sudden the logged in name will be displayed with other user name (Highlighted in green colour).</p>
