The WP4Covid site package requires PHP 7+ and best recommended version is PHP 7.0 or PHP 7.2.
Right now PHP 7.0 and 7.2 are the safest PHP version for online marketers due to many other themes/plugins don't support PHP 7.4 yet.
Here is how you can update your PHP to 7+:
- Login to cPanel
- Find the "Select PHP Version" menu: https://prnt.sc/r5q9a8
Then select PHP 7.0 or 7.2 from the available option.
When you're still on that page, it is also recommended if you can increase these PHP limit:
Click the Switch to PHP Options button: https://prnt.sc/r63kqo
Then there will be an options to adjust/increase those 4 settings above
PS. If you have the Cloud4WP hosting on us recently, you don't need to do anything. Those higher PHP value is our default setting.
