XF 1.5 Operate with PHP 7.4?

[Mr_Bob]

I know - this installation needs to be upgrade to 2.2.x. This is one community I just haven't had the time to port everything into 2 with yet along with the rest of this site, which runs on an outdated CMS. I know it's been two years . I promise my other sites are on 2.2.x.

Anyway, I'm moving this community over from an old shared hosting plan to my own VPS. I have PHP 8 and PHP 7.4 installed, and I'd really rather not install anything older that the 7.4. Will XF 1.5.x work OK with PHP 7.4? Does anyone have experience with that? I do plan on upgrading this particular site soon, but I need to move it over to the VPS because I'm letting the shared hosting plan die off.

Will XF 1.5.6 work with PHP 7.4?

Thank you.

Unlikely.

XF 1.5.6 came out February 2016.

PHP 7.4 was released November 2019.

Thanks @Brogan. Can I run the upgrade directly to XF 1.5.24 from 1.5.6. ?

I’ve been reluctant to make any changes since I have a number of customizations that I don’t want to break.
But my host is pushing me to get to PHP 7.4

Yes - the upgrade script will step through all interim versions.

It's possible you will need to address issues related to third party styles, and add-ons, template modifications, custom CSS, etc. when going from 1.5.6 to 1.5.24.

Just what I was afraid of ... thanks for the heads up.

One more Q if i may ... can you recommend a resource to help determine where these issues may exist in the upgrade path?

It’s been a while since I have made any meaningful changes to my installation and I want to be very careful not to break things too much.

Thank you.

It depends on the third party add-ons and styles you have installed.

You will need to check the resource thread of each one.
