We are self-hosted and in the process of updating our test installation from version 4.6.12.1 to 4.7.1

When updating the underlying systems we have started to encounter an error.  Prior to updating the forum software we updated the server to:  Debian 10 Buster, installed PHP 8.2. There was a MySQL update in there also. It's now running 10.3.34-MariaDB-0+deb10u1 Debian 10

Since this backend update when attempting to access the forums, we are encountering an error 500 on the UI, the only capturable error log is:  PHP Fatal error: Declaration of IPS\\Login
_Playnet::usernameIsInUse($username) must be compatible with IPS\\Login_Handler::usernameIsInUse($username, ?IPSMember $exclude = null) in var/www/forums/system/Login/Playnet.php on line 320

This error shows up when attempting to either a) login, or b) change theme from default.  As a result, the /admin area is not accessible to look into other possible causes or remediate.

IPS\\Login
_Playnet

That is a 3rd party app I think and you need to update it to being compatible with 4.7.x.

As mentioned by @DawPi, this is third party related so you will want to work with the author for assistance. It could be that it also is not compatible with PHP 8. 

You can use recovery mode to disable all third party applications/plugins as you do not have access to the ACP: 

 

 

installed PHP 8.2

IPS has barely started supporting PHP 8.1 with the 4.7 version and there are still some minor issues here and there. I  suggests testing the upgrade using PHP 8.0 to be safe.

It can take time to support newer versions of PHP as they are released. In this case however, 8.2 is still in beta, so we would not have begun looking at this as of yet.

Thanks for all of the responses.  Will rollback the php update and see what happens. 

What kind of value gets passed in IPS\\Login_Handler::usernameIsInUse($username, ?IPS:qMember $exclude = null) 

In this came the '3rd party app' is a php function that returns True/False/Null.  

 

Im not sure I understand the question you are asking there. If this is a 3rd party application you would need to speak to the author of that third party application.

It doesn't really matter what values are passed or returned. The current problem is that the parameters don't match the ones of the function the login is extending. As Marc said, you need to speak with the developer who wrote the code.

In case the original developer is no longer available you can find a new one from this list: https://invisioncommunity.com/third-party/providers/
