ERROR when upgrade Ubuntu

[egindo.co]

I have a droplet in digitalocean with Openlitespeed for running a wordpress based website using Ubuntu 18.04.3 LTS (GNU/Linux 4.15.0-55-generic x86_64) .
My OLS version :

LiteSpeed/1.4.49 Open (built: Mon Jul 15 18:56:17 UTC 2019)
module versions:
modpagespeed 2.2-1.11.33.4
cache 1.61
modinspector 1.1
uploadprogress 1.1
mod_security 1.1

The site working and running. But when I upgrade OS using apt upgrade, it show error like

WARNING: Module 7.2 ini file doesn't exist under /etc/php/7.2/mods-available

This error showing more than 30 lines.
I have try to copy php.ini to that directory but nothing change. It keep show error. Please help me to fix it. Thank you.

Hi @egindo.co ,

Those are just warning and can be ignored, it is from ubuntus PHP not from liteSpeed's.
May I know if site still loading fine?

Best

That openlitespeed wordpress image has already optimized, you can use some tuning and image optimize functions from lscache plugin to make your site lighter which means page load faster.
