Hi,
We upgraded from 8.0.3 and then as soon as we hit 8.2.0, it broke. We can get to the logon page of OpenEMR but when we click to login, we get error “This page isn’t working, If the problem continues, contact the site owner. HTTP ERROR 400”.
This is the only thing we see in the log "10.0.0.2 - - [21/Aug/2026:14:50:30 +0000] “POST /interface/main/main_screen.php?auth=login&site= HTTP/1.1” 400 - “https:///interface/login/login.php?site=default” “Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/151.0.0.0 Safari/537.36”.
Can you help us get this error resolved so we can finishing upgrading to 8.2.0 and then 8.3.0?
Thanks,
Samuel Eddinger
