If you're experiencing issues with OpenLiteSpeed 1.8.3 (such as login or API problems), you can safely downgrade to version 1.8.2 as a workaround.
Adam confirmed the issue here:
https://community.enhance.com/d/2709-inconsistent-login-experience/10
To downgrade:
/usr/local/lsws/admin/misc/lsup.sh -v 1.8.2
apt-mark hold openlitespeed
# To verify it:
apt-mark showhold
This will install 1.8.2 and prevent APT from auto-upgrading it in the future.
You can check your current OpenLiteSpeed version using
/usr/local/lsws/bin/lshttpd -v
To upgrade again later:
apt-mark unhold openlitespeed
apt install --reinstall openlitespeed
Tip: This downgrade is only needed on the main control panel server.
