Need help installing GD and Redis (Ubuntu 20)

Hello guys,

I am in no way a techy guy and I have just migrated a test WordPress site from shared hosting to OpenLiteSpeed + Ubuntu, on a VPS. I have managed to setup the Let's Encrypt but I couldn't handle the GD and Redis installations. I mean, I think I have installed them (I followed some tutorials here and on another site) but 1 of the WordPress plugins still says I don't have GD extension to convert WEBP images and LiteSpeed cache says I don't have Redis installed, even so, I have installed Redis + Redis-PHP with all the password configs and tests at the end.

Can someone give me a hand with this by explaining everything (including the complete basics, from A to Z), if possible of course? I've been struggling for 4-5 hours and I don't think I can do it.



Please make sure you have `lsphp73-common` extension installed.
Can you try creating a phpinfo page and check if redis and gd extension on it?

After package installed, restart PHP with command
killall lsphp
