wp-admin won’t load for users behind a Barracuda F600 firewall

It turns out it WAS the firewall after all. I asked their IT guy to create a ticket w/ Barracuda JIC. Barracuda found the issue and created a rule to allow it in. It had to do with IPS (not sure what that is).

Hata!: SQLSTATE[HY000] [1045] Access denied for user 'divattrend_liink'@'localhost' (using password: YES)
