Merge system startup error

[tkt55]

Hello!

I want to migrate from Xenfor 4.2.6 forum to MyBB version 1.8.38. I installed Mybb and the merge system, I get the following error message, I can't start the conversion program.
PHP version 8.3.10
MyBB version 1.8.38

Fatal error: Declaration of debugErrorHandler::error($type, $message, $file = null, $line = 0) must be compatible with errorHandler::error($type, $message, $file = null, $line = 0, $allow_output = true) in /www/wwwroot/androware.hu/androware/merge/resources/class_error.php on line 34

I found this solution but it didn't work.
