[RevCMS] 1.9.9 Client problems.

[Divine240]

Hello,

Recently i've began to set up my own Habbo Hotel, everything went well. Filled in everything in (using RevCMS 1.9.9.9)
But now there are several problems.

One, if i go on localhost/client it loads the client but afterwards it disconnects me.
Second, i have this strange error.
'' Deprecated: mysql_pconnect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in D:\xampp\htdocs\app\class.engine.php on line 48 ''

Third, if i log on my website and press Enter hotel it brings me to api.php, a voting website.

Anyone has some idea's how to solve this?
