PHP 7.4 + Compatibility Issues

Hi There,

I hope you are well,

I was wondering whether you could assist with the below report, our Web hosts are upgrading our servers which in turn means they will only be supporting PHP 7.4 and up. The report is generated through our Hosts PHP compatibility checker and indicates several issues.

If you could please advise what steps should be taken to ensure compatibility and continued functionality it would be greatly appreciated. Apologies for the messiness, unfortunately, this platform doesn’t allow pretty file uploads nor does it seem that I can send it to you in another way.
