How to update php version from 7.3 to 7.4 with OLWS on Ubuntu 20.04?


New Member
Can anyone help me update the PHP version of my WordPress website from PHP 7.3 to 7.4?
I am using Digital ocean hosting and have deployed my website using WordPress on Openlitespeed package from the digital ocean marketplace. However, I always end up getting a critical error on my website.

Here are the commands I tried on the digital ocean console -

sudo apt-get install software-properties-common
sudo add-apt-repository ppa: ondrej/php
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install -y php7.4

I also changed the script header by following Step 5 of this guide: (link)

I am a noob, so if anyone can share a step by step guide, it will be wonderful. Thank you so much in advance.

I would also recommend you should use Cyberpanel + OLS together since free cyberpanel has automated a lot of stuff including installation of multi php versions. It will make the life much easier.

but you can not install cyberpanel on your exiting OLS, it should be a bare OS.
I actually don't want to use cyberpanel as it consumes a lot of resources on my $5 droplet.

I am in @saz99 previous situation with 7.3 on Digital Ocean Hosting for a Wordpress website.
Did @Cold-Egg suggestion, thank you for that. Installing PHP 7.4.9

But, when I do PHP --version, it shows 7.3.17 not 7.4
And the same happens at Wordpress, is current running 7.3.17.

So, I do appreciate all your comments in advance for these questions:
1. How to enable PHP 7.4
2. How to delete PHP 7.3
3. And if is safe to delete PHP 7.3 after enable 7.4

Thanks for all



It should works on WordPress site, did you restart php yet?
killall -9 lsphp
PHP --version shows 7.3.17 is normal, because it has a softlink to lsphp73. Feel free to use follow command to link php74
ln -sfn /usr/local/lsws/lsphp74/bin/php /usr/bin/php
Please keep php73 exist
