To fix the error "PHP Warning: A non-numeric value encountered in..." with PHP 7.1.26

admincp/arcade.php

Find:

	if (substr($bbuserinfo['tzoffset'],1,0) == "+")
	{
	
		 $temptime = $temptime + strval(substr($bbuserinfo['tzoffset'],1)) * 3600;
	}
	else
	{
	
		 $temptime = $temptime - strval(substr($bbuserinfo['tzoffset'],1)) * 3600;
	}

change to

		if (substr($bbuserinfo['tzoffset'],1,0) == "+")
	{
	
		 $temptime = $temptime + strval((int)substr($bbuserinfo['tzoffset'],1)) * 3600;
	}
	else
	{
	
		 $temptime = $temptime - strval((int)substr($bbuserinfo['tzoffset'],1)) * 3600;
	}
