If you can't figure out how to install it with those instructions you shouldn't really be installing a panel.
#1 You import the dayz.sql file located in the folder called ' sql ' to the same database you have the server tables in ( MySQL )
#2 You rename the config.php-dist file in the main folder of the panel to config.php and then configure it with the right information
Set error_reporting in your php.ini to E_ALL & ~E_DEPRECATED & ~E_STRICT
For the stats page error create an issue at the page below so that Wriley can take a look at it as I currently do not have access to a 1.8.1 database. (I might have one around somewhere actually, hmm.) https://github.com/R4Z0R49/DayZAdmin/issues
