Old IP jumping in

[sci2tech]

There 3 files named ispcp.conf:
/etc/apache2/sites-available/ispcp.conf
/etc/ispcp/ispcp.conf
/etc/ispcp/apache/working/ispcp.conf.

/etc/ispcp/ispcp.conf is changed ONLY during updates from RC to RC, and values are taken from a copy of old ispcp.conf. Once you modify here NOTHING will revert your modifications.
But if you change /etc/apache2/sites-available/ispcp.conf you MUST also change /etc/ispcp/apache/working/ispcp.conf otherwise first will be overwritten by second on first time that you run engine requests. Hope this clarify a little.
