XF 1.4 "An unexpected error occurred" For one user



I seem, to be having an issue where one user only who tries to log in, gets this message ""An unexpected error occurred"


Well-known member
What does it say in your server logs (go to your xenforo admin page)


also, get him to clear his cache, it could be a corrupt cookie


While I checked to see what the server logs said, as soon as I clicked on it all of a sudden my forum changed and now has this issue
