XF 2.2 Error message when trying to put board in debug mode

[RobParker]

When trying to enable debug mode I get this error on every page:

An exception occurred: [ErrorException] [E_DEPRECATED] Return type of XF\Session\Session::offsetExists($key) should either be compatible with ArrayAccess::offsetExists(mixed $offset): bool, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in src/XF/Session/Session.php on line 175

Any ideas?

Ah looks like it's this https://xenforo.com/community/threads/php-8-1-compatibility.198874/ and I'm still running 2.2.6.

I assume there's no short-term solution to get debug mode working with 2.2.6 on PHP8.1?

(need to fix some big template edits so held off updating for a while).

Running PHP 8.1 or 8.2 maybe?

2.2.14 is fully compatible with 8.1

Yup, 8.1 but not updated XF for a while.
