XF 2.0 Upgrade Error

[JamesBrown]

Upgrading a forum from 1.5 to 2.

I've uploaded the files but when I point to the install directory I get the following error. Can anyone help me with this? Thanks

What 1.5 version are you running?

 

[JamesBrown]

I don’t recall. And right now I can’t get access to find out.

This is a kind of known issue which is fixed in XF 2.0.10 which is yet to be released.

However, the simplest way of resolving it is to upgrade your server so it runs at least PHP 7.0 (though we'd recommend PHP 7.2 if possible). Often it is simple to change the PHP version in your hosting panel or your host may be able to do it for you.

Thanks, Chris, I for some reason still had that domain sat at php5. Sorted it's now installing as I type. Cheers
