After Database restoration clients are not communicating with SEPM

Hi,

I am facing some issues with SEPM so I run the Manager configuration wizard with the intention to repair the SEPM after completing the wizard I restored the database with backup as on date of 31 March 2014 around 900 clients are added to SEPM at that time .

Restoration of database completed sucessfully but the issue is that clients are not communicating with SEPM manager are all of them showing Offline and I am also getting error of Apache again and again on the server on which SEPM is installed.

Please guide me what I have to do to make these clients again communicating with SEPM abd to fix this Apache error.

Regards
