Error formatting wp-config.php

Hello everyone. I posted this question on this question on the Italian support forum. Unfortunately, no one have responded to me yet.

Some days ago i was modelling my wp-config.php file manually with NotePad (microsoft).
Everything fine up to i saved this file and sent it to my server. The site didn’t work anymore. Reopening this file i saw that line were changed… (Everything became wrong!). This is the “Broken” file

<?php/** * The base configurations of the WordPress. * * This file has the following configurations: MySQL settings, Table Prefix, * Secret Keys, WordPress Language, and ABSPATH.

'wp-settings.php');

(I have hidden “Parte tolta” strings)

I rebuilt this file by myself and now the site seems to work well.
But some plug-in give me an error like this:
Fatal error: Call to undefined function get_site_allowed_themes() in /membri/milesimarco/wp-content/plugins/bp-groupblog/bp-groupblog-admin.php on line 310
(/membri/milesimarco is the part in common of every plug-in give me an error ??

I think the problem is in the last broken-file part (/** Sets up WordPress vars and included files. */)
In fact when i rewrote the file i didn’t copy the last part (i don’t kow how to format these lines….)

If you think this can be the problem, please tell me. I’d appreciate also if you can tell me how to rebuilt THE LAST PART of this file (for a medium-expert this will take less than 2 minutes… ) after this line:
/** Sets up WordPress vars and included files. */
