Installation errors

[Fox Mc Cloud]

I have a few errors on my forum.


The errors are:
On my vBulletin forum (http://www.tibiacity.org/forum/) I can't do anything because I get the next error:
Warning: array_keys() [function.array-keys]: The first argument should be an array in /includes/functions.php on line 3503
Warning: Invalid argument supplied for foreach() in /includes/functions.php on line 3503
This error came with transfering the forum from Siteground to Netfirms, and I don't know what it means neither how to fix it. I looked up the line and it says:
foreach (array_keys($vbulletin->forumcache) AS $forumid)


They came when I moved my forum from my old to my new host.

Please upload the file tools.php from the 'do_not_upload' folder in your vBulletin distribution to your admincp folder. Now point your browser to www.myboard.com/admincp/tools.php and choose to rebuild the datastore cache.

Once your problem is resolved please remove tools.php again.

Fatal error: Call to undefined function mysqli_init() in /mnt/w0000/d37/s01/b0291d4a/www/tibiacity.org/forum/includes/class_core.php on line 1021


I don't see anything anymore now.

Set your config.php to use mysql, and not mysqli.

That didn't work neither but I contacted my host and it was just my database password that was too long; thanks for the help.
