New hosting -- my board has broken

[hawork]

I moved all my files from the last hosting to the new one and uploaded the database without apparent mistakes. I configured my config.php with the information of the new hosting and the error when I try to get into the forum is:

Warning: array_keys() [function.array-keys]: The first argument should be an array in /includes/functions.php on line 3699

Warning: Invalid argument supplied for foreach() in /includes/functions.php on line 3699

Parse error: syntax error, unexpected '=' in /home/noticia/public_html/foroatletismo/foro/global.php(560) : eval()'d code on line 5

Parse error: syntax error, unexpected '=' in /home/noticia/public_html/foroatletismo/foro/global.php(561) : eval()'d code on line 40

Fatal error: Call to undefined function: print_portal_output() in /home/noticia/public_html/foroatletismo/index.php on line 44

If I change in config.php form mysql to mysqli, then the only error will be:

Fatal error: Call to undefined function: mysqli_init() in /home/noticia/public_html/foroatletismo/foro/includes/class_core.php on line 1030

Why is this happening? I would appreciate your help!

The first error is related to vBACMPS, if I am not mistaken. Reinstall it, making sure to follow the instructions exactly.

The second one (I think) is because you have mysql, not mysqli.

Thanks for anwering kall

So, I'll have to put mysql in config.php and reinstall vbadvanced. But the problem is that I have all the files mixed up with the vbulletin ones so, how can I do it?

PS: I don't have access to the admincp...
